It is demonstrated that provided a theory involves a minimal length this theory must be free from such infinitesimal quantities asinfinitely small variations in surface of the holographic screen its volume and entropy The corresponding infinitesimal quantitiesin this case must be replaced by the ldquominimal variations possiblerdquomdashfinite quantities dependent on the existent energies As a resultthe initial low-energy theory (quantum theory or general relativity) inevitably must be replaced by a minimal length theory thatgives very close results but operates with absolutely other mathematical apparatus
At the present time all high-energy generalizations (limits)of the basic components in fundamental physics (quantumtheory [1] and gravity [2]) of necessity lead to a minimallength on the order of the Planck length 119897min prop 119897
119875 This
follows from string theory [3ndash6] loop quantum gravity [7]and other approaches [8ndash22]
But it is clear that provided a minimal length exists itis existent at all the energy scales and not at high (Planckrsquos)scales only
What is inferred on this basis for real physics At least itis suggested that the use of infinitesimal quantities 119889119909
120583in a
mathematical apparatus of both quantum theory and gravityis incorrect despite the fact that both these theories give theresults correlating well with the experiment (eg [23])
Indeed in all cases the infinitesimal quantities 119889119909120583bring
about an infinitely small length 119889119904 [2]
1198891199042= 119892120583]119889119909120583119889119909] (1)
that is inexistent because of 119897minThe same is true for any function Υ dependent only on
different parameters 119871119894whose dimensions of length of the
exponents are equal to or greater than 1 ]119894ge 1
Υ equiv Υ (119871]119894119894) (2)
Obviously the infinitely small variation 119889Υ of Υ is senselessas according to (2) we have
119889Υ equiv 119889Υ (]119894119871]119894minus1119894
119889119871119894) (3)
But because of 119897min the infinitesimal quantities 119889119871119894make no
sense and hence 119889Υmakes no sense tooInstead of these infinitesimal quantities it seems reason-
able to denote them as ldquominimal variations possiblerdquo Δmin ofthe quantity 119871 having the dimension of length that is thequantity
Δmin119871 = 119897min (4)
And then
ΔminΥ equiv ΔminΥ (]119894119871]119894minus1119894
Δmin119871 119894) = ΔminΥ (]119894119871]119894minus1119894
119897min)
(5)
However the ldquominimal variations possiblerdquo of any quan-tity having the dimensions of length (4) which are equal to119897min prop 119897
119875require according to the Heisenberg Uncertainty
Principle (HUP) [24] maximal momentum 119901max prop 119875119875119897
and energy 119864max prop 119864119875 Here 119897
119875 119875119875119897 119864119875are Planckrsquos length
momentum and energy respectivelyBut at low energies (far from the Planck energy) there are
no such quantities and hence in essence Δmin119871 = 119897min prop
119897119875(4) corresponds to the high-energy (Planckrsquos) case only

For the energies lower than Planckrsquos energy the ldquominimalvariations possiblerdquo Δmin119871 of the quantity 119871 having thedimensions of lengthmust be greater than 119897min and dependenton the present 119864
Δmin equiv Δmin119864 Δmin119864119871 gt 119897min (6)
Besides as we have a minimal length unit 119897min it isclear that any quantity having the dimensions of length isldquoquantizedrdquo that is its valuemeasured in the units 119897min equalsan integer number and we have
119871 = 119873119871119897min (7)
where119873119871is positive integer number
Theproblem is that how the ldquominimal variations possiblerdquoΔmin119864 (6) are dependent on the energy or similarly on thescales of the measured lengths
To solve the above-mentioned problem initially we canuse the space-time quantum fluctuations (STQF) with regardto quantum theory and gravity
The definition (STQF) is closely associated with thenotion of ldquospace-time foamrdquo The notion ldquospace-time foamrdquointroduced byWheeler about 60 years ago for the descriptionand investigation of physics at Planckrsquos scales (EarlyUniverse)[25 26] is fairly settled Despite the fact that in the last decadenumerous works have been devoted to physics at Planckrsquosscales within the scope of this notion for example [27ndash46]by this time still their is no clear understanding of the ldquospace-time foamrdquo as it is
On the other hand it is undoubtful that a quantum theoryof the Early Universe should be a deformation of the well-known quantum theory
In my works with colleagues [47ndash56] I have put forwardone of the possible approaches to resolution of a quantumtheory at Planckrsquos scales on the basis of the density matrixdeformation
In accordance with the modern concepts the space-timefoam [26] notion forms the basis for space-time at Planckrsquosscales (Big Bang) This object is associated with the quantumfluctuations generated by uncertainties in measurements ofthe fundamental quantities inducing uncertainties in anydistance measurement A precise description of the space-time foam is still lacking along with an adequate quantumgravity theory But for the description of quantum fluctua-tions we have a number of interesting methods (eg [36ndash46 57 58])
In what follows we use the terms and symbols from [38]Then for the fluctuations 120575119897 of the distance 119897 we have thefollowing estimate
(120575119897)120574≳ 119897120574

where 0 lt 120574 le 1 coefficient 120573 is of order 1 and 120582119897equiv 119897119875119897
From (8) and (9) we can derive the quantum fluctuationsfor all the primary characteristics specifically for the time(120575119905)120574 energy (120575119864)
120574 and metrics (120575119892
120583])120574 In particular for(120575119892120583])120574 we can use formula (10) in [38]
(120575119892120583])120574≳ 120582120574 (10)
Further in the text it is assumed that the theory involvesa minimal length on the order of Planckrsquos length
119897min prop 119897119875 (11)
or similarly
119897min = 120585119897119875 (12)
where the coefficient 120585 is on the order of unity tooIn this case the origin of the minimal length is not
important For simplicity we assume that it comes from thegeneralized uncertainty principle (GUP) that is an extensionof HUP for Planckrsquos energies where gravity must be takeninto consideration [3ndash22]

Therefore in this case replacement of Planckrsquos length bythe minimal length in all the above formulae is absolutelycorrect and is used without detriment to the generality [59]
119897119875997888rarr 119897min (14)
Thus 120582119897equiv 119897min119897 and then (8)ndash(10) upon the replacement
of (14) remain unchangedAs noted in the overview [38] the value 120574 = 23 derived
in [57 58] is totally consistent with the Holographic Principle[60ndash63]
The following points of importance should be noted [59](11) It is clear that at Planckrsquos scales that is at theminimal
length scales
119897 997888rarr 119897min (15)
models for different values of the parameter 120574 are coincident(12) As noted specifically in (7) provided some quantity
has a minimal measuring unit values of this quantity aremultiples of this unit
Naturally any quantity having a minimal measuring unitis uniformly discrete
The latter property is not met in particular by the energy119864
As 119864 sim 1119897 where 119897 is measurable scale the energy 119864 is adiscrete but nonuniformquantity It is clear that the differencebetween the adjacent values of 119864 is the less the lower 119864 Inother words for 119897 ≫ 119897min that is
119864 ≪ 119864119875 (16)
119864 becomes a practically continuous quantity

(13) In fact the parameter 120582119897was introduced earlier
in [47ndash56] as a deformation parameter on going from thecanonical quantum mechanics to the quantum mechanics atPlanckrsquos scales (Early Universe) that are considered to be thequantum mechanics with the fundamental length (QMFL)

The deformation is understood as an extension of aparticular theory by inclusion of one or several additionalparameters in such a way that the initial theory appears inthe limiting transition [64]
Obviously everywhere apart from the limiting point120582119909= 1 or 119909 = 119897min we have
120582119909= radic120572119909 (18)
From (17) it is seen that at the limiting point 119909 = 119897minthe parameter 120572
119909is not defined due to the appearance of
singularity [47ndash56] But at this point its definition may beextended (regularized)
The parameter 120572119897has the following clear physical mean-

is the well-known Bekenstein-Hawking formula for the blackhole entropy in the semiclassical approximation [65 66] forthe black hole event horizon surface 119860 with the character-istics linear dimension (ldquoradiusrdquo) 119877 = 119897 This is especiallyobvious in the spherically symmetric case
In what follows we use both parameters 120582119909and 120572
119909
Turning back to the introductory section of this work andto the definition Δmin119864119871 we assume the following
1003816100381610038161003816Δmin1198641198711003816100381610038161003816 =

100381610038161003816100381610038161003816min (21)
where |(120575119871)120574|min is from formula (9) 120574 is fixed parameter
from formulae (8) and (9) and 119864 = 119888ℎ119871In physics and in thermodynamics in particular the
extensive quantities or parameters are those proportionalto the mass of a system or to its volume Proceeding fromdefinition (2) of the function Υ(119871
]119894119894) one can generalize this
notion taking as a generalized extensive quantity (GEQ) ofsome spatial system Ω the function dependent only on thelinear dimensions of this system with the exponents no lessthan 1
The function Υ(119871]119894119894) ]119894ge 1 (2) is GEQ of the system Ω
with the characteristic linear dimensions 119871119894 119894 = 1 119899 or
identically a sumof the systemsΩ119894 119894 = 1 119899 each ofwhich
has its individual characteristic linear dimension 119871119894
Then from the initial formulae (2)ndash(6) it directly followsthat provided the minimal length 119897min is existent there are noinfinitesimal variations of GEQ
In the first place this is true for such simplest objects asthe 119899-dimensional sphere 119861
119899 119899 ge 2 whose surface area (area
of the corresponding hypersphere 119878119899) and volume 119881
119899repre-
sent GEQs and are equal to the following
119878119899= 119899119862119899119877119899minus1
119881119899= 119862119899119877119899 (22)
where 119877mdashradius of a sphere the length of which is a charac-teristic linear size 119862
119899= 1205871198992
Γ((1198992) + 1) and Γ(119909) is agamma-function
Of course the same is true for the 119899-dimensional cube (orhypercube)119860
119899 its surface area and its volume are GEQs and
a length of its edge is a characteristic linear dimensionProvided 119897min exists there are no infinitesimal increments
for both the surface area and volume of 119860119899or 119861119899 only
minimal variations possible for these quantities are the caseIn what follows we consider only the spatial systems
whose surface areas and volumes are GEQsLet us consider a simple but very important example of
gravity in horizon spacesGravity and thermodynamics of horizon spaces and their
interrelations are currently most actively studied [67ndash79] Letus consider a relatively simple illustrationmdashthe case of a staticspherically symmetric horizon in space-time the horizonbeing described by the metric

The horizon location will be given by a simple zero of thefunction 119891(119903) at the radius 119903 = 119886
This case is studied in detail by Padmanabhan in hisworks[67 78] and by the author of this paper in [80] We usethe notation system of [78] Let for simplicity the space bedenoted byH
It is known that for horizon spaces one can introduce thetemperature that can be identified with an analytic continua-tion to imaginary time In the case under consideration ([78]Equation (116))

Therewith the conditions 119891(119886) = 0 and 1198911015840(119886) = 0 must
be fulfilledThen at the horizon 119903 = 119886 Einsteinrsquos equations have the

to consider (25) in a new notation expressing 119886 in terms ofthe corresponding deformation parameter 120572 In what followswe omit the subscript in formula (17) of 120572
119909 where the context
implies which index is the case In particular here we use 120572
instead of 120572119886 Then we have

that is the Gaussian curvature 119870119886is a solution of Einstein
equations in this caseThen we examine different cases of thesolution (33) with due regard for considerations of formula(21)
(21) First let us assume that 119886 ≫ 119897min As according to(7) the radius 119886 is quantized we have 119886 = 119873
119886119897min with the
natural number 119873119886≫ 1 Then it is clear that the Gaussian
curvature119870119886= 1119886
2asymp 0 takes a (nonuniform) discrete series
of values close to zero and within the factor 11198972min this seriesrepresents inverse squares of natural numbers

Let us return to formulas (9) and (21) for 119897 = 119886 consider1003816100381610038161003816100381610038161003816((120575119886)

where 120573 in this case contains the proportionality factor thatrelates 119897min and 119897
119875
Then according to (21) 119886plusmn1
is a measurable value of theradius 119903 following after 119886 and we have
(119886plusmn1)120574equiv 119886 plusmn ((120575119886)

But as 119873119886≫ 1 for sufficiently large 119873
119886and fixed 120574 the
bracketed expression in rhs (36) is close to 1

And this is the case for sufficiently large values of 119873119886
for any value of the parameter 120574 and for 120574 = 1 as wellcorresponding to the absolute minimum of fluctuations asymp
119897min or more precisely to 120573119897min However as all the quantitiesof the length dimension are quantized and the factor 120573 is onthe order of 1 actually we have 120573 = 1
Because of this provided the minimal length is involved119897min (9) is read as
10038161003816100381610038161003816(120575119897)1
10038161003816100381610038161003816min= 119897min (40)
But according to (12) 119897min = 120585119897119875is on the order of
Planckrsquos length and it is clear that the fluctuation |(120575119897)1|min
corresponds to Planckrsquos energies and Planckrsquos scales TheGaussian curvature119870
119886 due to its smallness (119870
119886≪ 1 up to the
constant factor 119897minus2min) and smooth variations independent of 120574(formulas (36)ndash(39)) is insensitive to the differences betweenvarious values of 120574
Consequently for sufficiently small Gaussian curvature119870119886 we can take any parameter from the interval 0 lt 120574 le 1 as
120574It is obvious that the case 120574 = 1 that is |(120575119897)
1|min = 119897min
is associated with infinitely small variations 119889119886 of the radius119903 = 119886 in the Riemannian geometry
Since then119870119886is varying practically continuously in terms
of 119870119886up to the constant factor we can obtain the following
expression
119889 [119871 (119870119886)] = 119889 [119875 (119870
119886)] (41)

But in fact as in this case the energies are low it is morecorrect to consider
119871 ((119870119886plusmn1
)120574)
minus 119871 (119870119886) = [119875 (119870

120574[119875 (119870
119886)]
(43)
where 120574 lt 1 rather than (41)In view of the foregoing arguments (21) the difference
between (43) and (41) is insignificant and it is perfectlycorrect to use (41) instead of (43)
(22) Now we consider the opposite case or the transitionto the ultraviolet limit
119886 997888rarr 119897min = 120581119897min (44)
That is
119886 = 120581119897min (45)
Here 120581 is on the order of 1Taking into consideration point (11) stating that in this
case models for different values of the parameter 120574 arecoincident by formula (40) for any 120574 we have
100381610038161003816100381610038161003816(120575119897)120574

10038161003816100381610038161003816min= 119897min (46)
But in this case the Gaussian curvature119870119886is not a ldquosmall
valuerdquo continuously dependent on 119886 taking according to(39) a discrete series of values119870
119886 119870119886plusmn1
119870119886plusmn2
Yet (25) similar to (32) (33) is valid in the semiclassical
approximation only that is at low energiesThen in accordance with the above arguments the
limiting transition to high energies (44) gives a discrete chainof equations or a single equation with a discrete set ofsolutions as follows

and so on Here Θ(119870119886) is some function that in the limiting
transition to low energies must reproduce the low-energyresult to a high degree of accuracy that is 119875(119870
119886) appears for
119886 ≫ 119897min from formula (33)
lim119870119886rarr0
Θ(119870119886) = 119875 (119870
119886) (48)
In general Θ(119870119886) may lack coincidence with the high-
energy limit of the momentum-energy tensor trace (if any)
lim119886rarr 119897min
119875 (119870119886) (49)
At the same timewhenwenaturally assume that the staticspherically-symmetric horizon space-time with the radiusof several Planckrsquos units (45) is nothing else but a microblack hole then the high-energy limit (49) is existing andthe replacement of Θ(119870
119886) by 119875(119870
119886) in rhs of the foregoing
equations is possible to give a hypothetical gravitationalequation for the event horizon micro black hole But aquestion arises for which values of the parameter 119886 (45) (or119870119886) is this valid and what is a minimal value of the parameter
120574 = 120574(119886) in this caseIn all the cases under study (21) and (22) the deforma-
tion parameter 120572119886(17) (120582
119886(18)) is within the constant factor
coincident with the Gaussian curvature 119870119886(resp radic119870
119886) that
is in essence continuous in the low-energy case and discretein the high-energy case
In this way the above-mentioned example shows thatdespite the absence of infinitesimal spatial-temporal incre-ments owing to the existence of 119897min and the essentialldquodiscretenessrdquo of a theory this discreteness at low energies isnot felt the theory being actually continuous The indicateddiscreteness is significant only in the case of high (Planckrsquos)energies
In [78] it is shown that the Einstein equation for horizonspaces in the differential formmay be written as a thermody-namic identity (the first principle of thermodynamics) ([78]formula (119))

where as noted above 119879 is temperature of the horizonsurface 119878 is corresponding entropy 119864 is internal energy and119881 is space volume
Note that because of the existing 119897min practically allquantities in (50) (except of 119879) represent GEQ Apparentlythe radius of a sphere 119903 = 119886 its volume 119881 and entropyrepresent such quantities

radius 119886Because of this there are no infinitesimal increments
of these quantities that is 119889119886 119889119881 119889119878 And provided 119897min isinvolved the Einstein equation for the above-mentioned casein the differential form (50) makes no sense and is uselessIf 119889119886 may be purely formerly replaced by 119897min then as thequantity 119897min is fixed it is obvious that ldquo119889119878rdquo and ldquo119889119881rdquo in (50)will be growing as 119886 and 119886
2 respectively And at low energiesthat is for large values of 119886 ≫ 119897min this naturally leads toinfinitely large rather than infinitesimal values
In a similar way it is easily seen that the ldquoEntropicApproach to Gravityrdquo [82] in the present formalism is invalidwithin the scope of the minimal length theory In fact theldquomain instrumentrdquo in [82] is a formula for the infinitesimalvariation 119889119873 in the bit numbers119873 on the holographic screenSwith the radius119877 andwith the surface area119860 ([82] formula(418))

(52)
As 119873 = 1198601198972
119875and 119860 represents GEQ it is clear that 119873 is
also GEQ and hence neither 119889119860 nor 119889119873makes sense
6 Advances in High Energy Physics
It is obvious that infinitesimal variations of the screensurface area 119889119860 are possible only in a continuous theoryinvolving no 119897min
When 119897min prop 119897119875is involved the minimal variation Δ119860 is
evidently associated with a minimal variation in the radius 119877
119877 997888rarr 119877 plusmn 119897min (53)
is dependent on 119877 and growing as 119877 for 119877 ≫ 119897min
Δplusmn119860 (119877) = (119860 (119877 plusmn 119897min) minus 119860 (119877)) prop (

119897min+ 1)
= plusmn2119873119877+ 1
(54)
where119873119877= 119877119897min as indicated above
But as noted above a minimal increment of the radius 119877equal to |Δmin119877| = 119897min prop 119897
119875corresponds only to the case
of maximal (Planckrsquos) energies or similarly to the parameter120574 = 1 in formula (21) However in [82] the considered lowenergies are far from the Planck energies and hence in thiscase in (21) 120574 lt 1 (53) and (54) are respectively replacedby

(56)
An increase of rhs in (56) with the growth of 119877 (oridentically of119873
119877) for 119877 ≫ 119897min is obvious
So if 119897min is involved formula (418) from [82] makes nosense similar to other formulae derived on its basis (419)(420) (422) (532)ndash(534) in [82] and similar to thederivation method for Einsteinrsquos equations proposed in thiswork
Proceeding from the principal parameters of this work120572119897(or 120582119897) the fact is obvious and is supported by formula (19)
given in this paper meaning that
120572minus1
119877sim 119860 (57)
That is small variations of 120572119877(low energies) result in large
variations of 120572minus1119877 as indicated by formula (54)
In fact we have no-go theoremsThe last statements concerning 119889119878 119889119873 may be explicitly
interpreted using the language of a quantum informationtheory as follows due to the existence of the minimal length119897min the minimal area 1198972min and volume 1198973min are also involvedand that means ldquoquantizationrdquo of the areas and volumes Asup to the known constants the ldquobit numberrdquo119873 from (52) andthe entropy 119878 from (51) are nothing else but
119878 =119860
41198972min 119873 =
119860
1198972min (58)
it is obvious that there is a ldquominimalmeasurerdquo for the ldquoamountof datardquo that may be referred to as ldquoone bitrdquo (or ldquoone qubitrdquo)
The statement that there is no such quantity as 119889119873 (andresp 119889119878) is equivalent to claiming the absence of 025 bit0001 bit and so on
This inference completely conforms to the Hooft-Susskind Holographic Principle (HP) [60ndash63] that includestwo main statements as follows
(a) All information contained in a particular spatialdomain is concentrated at the boundary of thisdomain
(b) A theory for the boundary of the spatial domainunder study should contain maximally one degree offreedom per Planckrsquos area 1198972
119875
In fact (but not explicitly) HP implicates the existence of119897min = 119897
119875 The existence of 119897min prop 119897
119875totally conforms to HP
providing its generalization Specifically without the loss ofgenerality 1198972
119875in point (b) may be replaced by 119897
2
minSo the principal inference of this work is as follows
provided the minimal length 119897min is involved its existencemust be taken into consideration not only at high but alsoat low energies both in a quantum theory and in gravityThis becomes apparent by rejection of the infinitesimalquantities associated with the spatial-temporal variations119889119909120583 In other words with the involvement of 119897min the
general relativity (GR) must be replaced by a (still unframed)minimal length gravitation theory that may be denoted asGrav119897min In their results GR and Grav119897min should be very closebut as regards their mathematical apparatus (instruments)these theories are absolutely different
Besides Grav119897min should offer a rather natural transitionfrom high to low energies
[119873119871asymp 1] 997888rarr [119873
119871≫ 1] (59)
and vice versa
[119873119871≫ 1] 997888rarr [119873
119871asymp 1] (60)
where 119873119871
is integer from formula (7) determining thecharacteristics scale of the lengths 119871 (energies 119864 sim 1119871 prop

For the energies lower than Planckrsquos energy the ldquominimalvariations possiblerdquo Δmin119871 of the quantity 119871 having thedimensions of lengthmust be greater than 119897min and dependenton the present 119864
Δmin equiv Δmin119864 Δmin119864119871 gt 119897min (6)
Besides as we have a minimal length unit 119897min it isclear that any quantity having the dimensions of length isldquoquantizedrdquo that is its valuemeasured in the units 119897min equalsan integer number and we have
119871 = 119873119871119897min (7)
where119873119871is positive integer number
Theproblem is that how the ldquominimal variations possiblerdquoΔmin119864 (6) are dependent on the energy or similarly on thescales of the measured lengths
To solve the above-mentioned problem initially we canuse the space-time quantum fluctuations (STQF) with regardto quantum theory and gravity
The definition (STQF) is closely associated with thenotion of ldquospace-time foamrdquo The notion ldquospace-time foamrdquointroduced byWheeler about 60 years ago for the descriptionand investigation of physics at Planckrsquos scales (EarlyUniverse)[25 26] is fairly settled Despite the fact that in the last decadenumerous works have been devoted to physics at Planckrsquosscales within the scope of this notion for example [27ndash46]by this time still their is no clear understanding of the ldquospace-time foamrdquo as it is
On the other hand it is undoubtful that a quantum theoryof the Early Universe should be a deformation of the well-known quantum theory
In my works with colleagues [47ndash56] I have put forwardone of the possible approaches to resolution of a quantumtheory at Planckrsquos scales on the basis of the density matrixdeformation
In accordance with the modern concepts the space-timefoam [26] notion forms the basis for space-time at Planckrsquosscales (Big Bang) This object is associated with the quantumfluctuations generated by uncertainties in measurements ofthe fundamental quantities inducing uncertainties in anydistance measurement A precise description of the space-time foam is still lacking along with an adequate quantumgravity theory But for the description of quantum fluctua-tions we have a number of interesting methods (eg [36ndash46 57 58])
In what follows we use the terms and symbols from [38]Then for the fluctuations 120575119897 of the distance 119897 we have thefollowing estimate
(120575119897)120574≳ 119897120574

where 0 lt 120574 le 1 coefficient 120573 is of order 1 and 120582119897equiv 119897119875119897
From (8) and (9) we can derive the quantum fluctuationsfor all the primary characteristics specifically for the time(120575119905)120574 energy (120575119864)
120574 and metrics (120575119892
120583])120574 In particular for(120575119892120583])120574 we can use formula (10) in [38]
(120575119892120583])120574≳ 120582120574 (10)
Further in the text it is assumed that the theory involvesa minimal length on the order of Planckrsquos length
119897min prop 119897119875 (11)
or similarly
119897min = 120585119897119875 (12)
where the coefficient 120585 is on the order of unity tooIn this case the origin of the minimal length is not
important For simplicity we assume that it comes from thegeneralized uncertainty principle (GUP) that is an extensionof HUP for Planckrsquos energies where gravity must be takeninto consideration [3ndash22]

Here1205721015840 is themodel-dependent dimensionless numericalfactor

=
2radic1205721015840119897119875
Therefore in this case replacement of Planckrsquos length bythe minimal length in all the above formulae is absolutelycorrect and is used without detriment to the generality [59]
119897119875997888rarr 119897min (14)
Thus 120582119897equiv 119897min119897 and then (8)ndash(10) upon the replacement
of (14) remain unchangedAs noted in the overview [38] the value 120574 = 23 derived
in [57 58] is totally consistent with the Holographic Principle[60ndash63]
The following points of importance should be noted [59](11) It is clear that at Planckrsquos scales that is at theminimal
length scales
119897 997888rarr 119897min (15)
models for different values of the parameter 120574 are coincident(12) As noted specifically in (7) provided some quantity
has a minimal measuring unit values of this quantity aremultiples of this unit
Naturally any quantity having a minimal measuring unitis uniformly discrete
The latter property is not met in particular by the energy119864
As 119864 sim 1119897 where 119897 is measurable scale the energy 119864 is adiscrete but nonuniformquantity It is clear that the differencebetween the adjacent values of 119864 is the less the lower 119864 Inother words for 119897 ≫ 119897min that is
119864 ≪ 119864119875 (16)
119864 becomes a practically continuous quantity

(13) In fact the parameter 120582119897was introduced earlier
in [47ndash56] as a deformation parameter on going from thecanonical quantum mechanics to the quantum mechanics atPlanckrsquos scales (Early Universe) that are considered to be thequantum mechanics with the fundamental length (QMFL)

where 119909 is the measuring scale 119897min sim 119897119901
The deformation is understood as an extension of aparticular theory by inclusion of one or several additionalparameters in such a way that the initial theory appears inthe limiting transition [64]
Obviously everywhere apart from the limiting point120582119909= 1 or 119909 = 119897min we have
120582119909= radic120572119909 (18)
From (17) it is seen that at the limiting point 119909 = 119897minthe parameter 120572
119909is not defined due to the appearance of
singularity [47ndash56] But at this point its definition may beextended (regularized)
The parameter 120572119897has the following clear physical mean-

is the well-known Bekenstein-Hawking formula for the blackhole entropy in the semiclassical approximation [65 66] forthe black hole event horizon surface 119860 with the character-istics linear dimension (ldquoradiusrdquo) 119877 = 119897 This is especiallyobvious in the spherically symmetric case
In what follows we use both parameters 120582119909and 120572
119909
Turning back to the introductory section of this work andto the definition Δmin119864119871 we assume the following
1003816100381610038161003816Δmin1198641198711003816100381610038161003816 =

100381610038161003816100381610038161003816min (21)
where |(120575119871)120574|min is from formula (9) 120574 is fixed parameter
from formulae (8) and (9) and 119864 = 119888ℎ119871In physics and in thermodynamics in particular the
extensive quantities or parameters are those proportionalto the mass of a system or to its volume Proceeding fromdefinition (2) of the function Υ(119871
]119894119894) one can generalize this
notion taking as a generalized extensive quantity (GEQ) ofsome spatial system Ω the function dependent only on thelinear dimensions of this system with the exponents no lessthan 1
The function Υ(119871]119894119894) ]119894ge 1 (2) is GEQ of the system Ω
with the characteristic linear dimensions 119871119894 119894 = 1 119899 or
identically a sumof the systemsΩ119894 119894 = 1 119899 each ofwhich
has its individual characteristic linear dimension 119871119894
Then from the initial formulae (2)ndash(6) it directly followsthat provided the minimal length 119897min is existent there are noinfinitesimal variations of GEQ
In the first place this is true for such simplest objects asthe 119899-dimensional sphere 119861
119899 119899 ge 2 whose surface area (area
of the corresponding hypersphere 119878119899) and volume 119881
119899repre-
sent GEQs and are equal to the following
119878119899= 119899119862119899119877119899minus1
119881119899= 119862119899119877119899 (22)
where 119877mdashradius of a sphere the length of which is a charac-teristic linear size 119862
119899= 1205871198992
Γ((1198992) + 1) and Γ(119909) is agamma-function
Of course the same is true for the 119899-dimensional cube (orhypercube)119860
119899 its surface area and its volume are GEQs and
a length of its edge is a characteristic linear dimensionProvided 119897min exists there are no infinitesimal increments
for both the surface area and volume of 119860119899or 119861119899 only
minimal variations possible for these quantities are the caseIn what follows we consider only the spatial systems
whose surface areas and volumes are GEQsLet us consider a simple but very important example of
gravity in horizon spacesGravity and thermodynamics of horizon spaces and their
interrelations are currently most actively studied [67ndash79] Letus consider a relatively simple illustrationmdashthe case of a staticspherically symmetric horizon in space-time the horizonbeing described by the metric

The horizon location will be given by a simple zero of thefunction 119891(119903) at the radius 119903 = 119886
This case is studied in detail by Padmanabhan in hisworks[67 78] and by the author of this paper in [80] We usethe notation system of [78] Let for simplicity the space bedenoted byH
It is known that for horizon spaces one can introduce thetemperature that can be identified with an analytic continua-tion to imaginary time In the case under consideration ([78]Equation (116))

Therewith the conditions 119891(119886) = 0 and 1198911015840(119886) = 0 must
be fulfilledThen at the horizon 119903 = 119886 Einsteinrsquos equations have the

to consider (25) in a new notation expressing 119886 in terms ofthe corresponding deformation parameter 120572 In what followswe omit the subscript in formula (17) of 120572
119909 where the context
implies which index is the case In particular here we use 120572
instead of 120572119886 Then we have

119886119897min with the

But as 119873119886≫ 1 for sufficiently large 119873

bracketed expression in rhs (36) is close to 1

As a result the Gaussian curvature119870119886plusmn1

in the case under study is only slightly different from119870119886
And this is the case for sufficiently large values of 119873119886
for any value of the parameter 120574 and for 120574 = 1 as wellcorresponding to the absolute minimum of fluctuations asymp
119897min or more precisely to 120573119897min However as all the quantitiesof the length dimension are quantized and the factor 120573 is onthe order of 1 actually we have 120573 = 1
Because of this provided the minimal length is involved119897min (9) is read as
10038161003816100381610038161003816(120575119897)1
10038161003816100381610038161003816min= 119897min (40)
But according to (12) 119897min = 120585119897119875is on the order of
Planckrsquos length and it is clear that the fluctuation |(120575119897)1|min
corresponds to Planckrsquos energies and Planckrsquos scales TheGaussian curvature119870
119886 due to its smallness (119870
119886≪ 1 up to the
constant factor 119897minus2min) and smooth variations independent of 120574(formulas (36)ndash(39)) is insensitive to the differences betweenvarious values of 120574
Consequently for sufficiently small Gaussian curvature119870119886 we can take any parameter from the interval 0 lt 120574 le 1 as
120574It is obvious that the case 120574 = 1 that is |(120575119897)
1|min = 119897min
is associated with infinitely small variations 119889119886 of the radius119903 = 119886 in the Riemannian geometry
Since then119870119886is varying practically continuously in terms
of 119870119886up to the constant factor we can obtain the following
expression
119889 [119871 (119870119886)] = 119889 [119875 (119870
119886)] (41)

But in fact as in this case the energies are low it is morecorrect to consider
119871 ((119870119886plusmn1

minus 119871 (119870119886) = [119875 (119870

(43)
where 120574 lt 1 rather than (41)In view of the foregoing arguments (21) the difference
between (43) and (41) is insignificant and it is perfectlycorrect to use (41) instead of (43)
(22) Now we consider the opposite case or the transitionto the ultraviolet limit
119886 997888rarr 119897min = 120581119897min (44)
That is
119886 = 120581119897min (45)
Here 120581 is on the order of 1Taking into consideration point (11) stating that in this
case models for different values of the parameter 120574 arecoincident by formula (40) for any 120574 we have

10038161003816100381610038161003816min= 119897min (46)
But in this case the Gaussian curvature119870119886is not a ldquosmall
valuerdquo continuously dependent on 119886 taking according to(39) a discrete series of values119870

Yet (25) similar to (32) (33) is valid in the semiclassical
approximation only that is at low energiesThen in accordance with the above arguments the
limiting transition to high energies (44) gives a discrete chainof equations or a single equation with a discrete set ofsolutions as follows

and so on Here Θ(119870119886) is some function that in the limiting
transition to low energies must reproduce the low-energyresult to a high degree of accuracy that is 119875(119870
119886) appears for
119886 ≫ 119897min from formula (33)
lim119870119886rarr0
Θ(119870119886) = 119875 (119870
119886) (48)
In general Θ(119870119886) may lack coincidence with the high-
energy limit of the momentum-energy tensor trace (if any)
lim119886rarr 119897min
119875 (119870119886) (49)
At the same timewhenwenaturally assume that the staticspherically-symmetric horizon space-time with the radiusof several Planckrsquos units (45) is nothing else but a microblack hole then the high-energy limit (49) is existing andthe replacement of Θ(119870
119886) by 119875(119870
119886) in rhs of the foregoing
equations is possible to give a hypothetical gravitationalequation for the event horizon micro black hole But aquestion arises for which values of the parameter 119886 (45) (or119870119886) is this valid and what is a minimal value of the parameter
120574 = 120574(119886) in this caseIn all the cases under study (21) and (22) the deforma-
tion parameter 120572119886(17) (120582
119886(18)) is within the constant factor
coincident with the Gaussian curvature 119870119886(resp radic119870
119886) that
is in essence continuous in the low-energy case and discretein the high-energy case
In this way the above-mentioned example shows thatdespite the absence of infinitesimal spatial-temporal incre-ments owing to the existence of 119897min and the essentialldquodiscretenessrdquo of a theory this discreteness at low energies isnot felt the theory being actually continuous The indicateddiscreteness is significant only in the case of high (Planckrsquos)energies
In [78] it is shown that the Einstein equation for horizonspaces in the differential formmay be written as a thermody-namic identity (the first principle of thermodynamics) ([78]formula (119))

where as noted above 119879 is temperature of the horizonsurface 119878 is corresponding entropy 119864 is internal energy and119881 is space volume
Note that because of the existing 119897min practically allquantities in (50) (except of 119879) represent GEQ Apparentlythe radius of a sphere 119903 = 119886 its volume 119881 and entropyrepresent such quantities

of these quantities that is 119889119886 119889119881 119889119878 And provided 119897min isinvolved the Einstein equation for the above-mentioned casein the differential form (50) makes no sense and is uselessIf 119889119886 may be purely formerly replaced by 119897min then as thequantity 119897min is fixed it is obvious that ldquo119889119878rdquo and ldquo119889119881rdquo in (50)will be growing as 119886 and 119886
2 respectively And at low energiesthat is for large values of 119886 ≫ 119897min this naturally leads toinfinitely large rather than infinitesimal values
In a similar way it is easily seen that the ldquoEntropicApproach to Gravityrdquo [82] in the present formalism is invalidwithin the scope of the minimal length theory In fact theldquomain instrumentrdquo in [82] is a formula for the infinitesimalvariation 119889119873 in the bit numbers119873 on the holographic screenSwith the radius119877 andwith the surface area119860 ([82] formula(418))

As 119873 = 1198601198972
119875and 119860 represents GEQ it is clear that 119873 is
also GEQ and hence neither 119889119860 nor 119889119873makes sense

It is obvious that infinitesimal variations of the screensurface area 119889119860 are possible only in a continuous theoryinvolving no 119897min
When 119897min prop 119897119875is involved the minimal variation Δ119860 is
evidently associated with a minimal variation in the radius 119877
119877 997888rarr 119877 plusmn 119897min (53)
is dependent on 119877 and growing as 119877 for 119877 ≫ 119897min
Δplusmn119860 (119877) = (119860 (119877 plusmn 119897min) minus 119860 (119877)) prop (

= plusmn2119873119877+ 1
(54)
where119873119877= 119877119897min as indicated above
But as noted above a minimal increment of the radius 119877equal to |Δmin119877| = 119897min prop 119897
119875corresponds only to the case
of maximal (Planckrsquos) energies or similarly to the parameter120574 = 1 in formula (21) However in [82] the considered lowenergies are far from the Planck energies and hence in thiscase in (21) 120574 lt 1 (53) and (54) are respectively replacedby

An increase of rhs in (56) with the growth of 119877 (oridentically of119873
119877) for 119877 ≫ 119897min is obvious
So if 119897min is involved formula (418) from [82] makes nosense similar to other formulae derived on its basis (419)(420) (422) (532)ndash(534) in [82] and similar to thederivation method for Einsteinrsquos equations proposed in thiswork
Proceeding from the principal parameters of this work120572119897(or 120582119897) the fact is obvious and is supported by formula (19)
given in this paper meaning that
120572minus1
119877sim 119860 (57)
That is small variations of 120572119877(low energies) result in large
variations of 120572minus1119877 as indicated by formula (54)
In fact we have no-go theoremsThe last statements concerning 119889119878 119889119873 may be explicitly
interpreted using the language of a quantum informationtheory as follows due to the existence of the minimal length119897min the minimal area 1198972min and volume 1198973min are also involvedand that means ldquoquantizationrdquo of the areas and volumes Asup to the known constants the ldquobit numberrdquo119873 from (52) andthe entropy 119878 from (51) are nothing else but
119878 =119860
41198972min 119873 =
119860
1198972min (58)
it is obvious that there is a ldquominimalmeasurerdquo for the ldquoamountof datardquo that may be referred to as ldquoone bitrdquo (or ldquoone qubitrdquo)
The statement that there is no such quantity as 119889119873 (andresp 119889119878) is equivalent to claiming the absence of 025 bit0001 bit and so on
This inference completely conforms to the Hooft-Susskind Holographic Principle (HP) [60ndash63] that includestwo main statements as follows
(a) All information contained in a particular spatialdomain is concentrated at the boundary of thisdomain
(b) A theory for the boundary of the spatial domainunder study should contain maximally one degree offreedom per Planckrsquos area 1198972
119875
In fact (but not explicitly) HP implicates the existence of119897min = 119897
119875 The existence of 119897min prop 119897
119875totally conforms to HP
providing its generalization Specifically without the loss ofgenerality 1198972
119875in point (b) may be replaced by 119897
2
minSo the principal inference of this work is as follows
provided the minimal length 119897min is involved its existencemust be taken into consideration not only at high but alsoat low energies both in a quantum theory and in gravityThis becomes apparent by rejection of the infinitesimalquantities associated with the spatial-temporal variations119889119909120583 In other words with the involvement of 119897min the
general relativity (GR) must be replaced by a (still unframed)minimal length gravitation theory that may be denoted asGrav119897min In their results GR and Grav119897min should be very closebut as regards their mathematical apparatus (instruments)these theories are absolutely different
Besides Grav119897min should offer a rather natural transitionfrom high to low energies

and vice versa

(13) In fact the parameter 120582119897was introduced earlier
in [47ndash56] as a deformation parameter on going from thecanonical quantum mechanics to the quantum mechanics atPlanckrsquos scales (Early Universe) that are considered to be thequantum mechanics with the fundamental length (QMFL)

where 119909 is the measuring scale 119897min sim 119897119901
The deformation is understood as an extension of aparticular theory by inclusion of one or several additionalparameters in such a way that the initial theory appears inthe limiting transition [64]
Obviously everywhere apart from the limiting point120582119909= 1 or 119909 = 119897min we have
120582119909= radic120572119909 (18)
From (17) it is seen that at the limiting point 119909 = 119897minthe parameter 120572
119909is not defined due to the appearance of
singularity [47ndash56] But at this point its definition may beextended (regularized)
The parameter 120572119897has the following clear physical mean-

is the well-known Bekenstein-Hawking formula for the blackhole entropy in the semiclassical approximation [65 66] forthe black hole event horizon surface 119860 with the character-istics linear dimension (ldquoradiusrdquo) 119877 = 119897 This is especiallyobvious in the spherically symmetric case
In what follows we use both parameters 120582119909and 120572
119909
Turning back to the introductory section of this work andto the definition Δmin119864119871 we assume the following
1003816100381610038161003816Δmin1198641198711003816100381610038161003816 =

where |(120575119871)120574|min is from formula (9) 120574 is fixed parameter
from formulae (8) and (9) and 119864 = 119888ℎ119871In physics and in thermodynamics in particular the
extensive quantities or parameters are those proportionalto the mass of a system or to its volume Proceeding fromdefinition (2) of the function Υ(119871
]119894119894) one can generalize this
notion taking as a generalized extensive quantity (GEQ) ofsome spatial system Ω the function dependent only on thelinear dimensions of this system with the exponents no lessthan 1
The function Υ(119871]119894119894) ]119894ge 1 (2) is GEQ of the system Ω
with the characteristic linear dimensions 119871119894 119894 = 1 119899 or
identically a sumof the systemsΩ119894 119894 = 1 119899 each ofwhich
has its individual characteristic linear dimension 119871119894
Then from the initial formulae (2)ndash(6) it directly followsthat provided the minimal length 119897min is existent there are noinfinitesimal variations of GEQ
In the first place this is true for such simplest objects asthe 119899-dimensional sphere 119861
119899 119899 ge 2 whose surface area (area
of the corresponding hypersphere 119878119899) and volume 119881
119899repre-
sent GEQs and are equal to the following
119878119899= 119899119862119899119877119899minus1
119881119899= 119862119899119877119899 (22)
where 119877mdashradius of a sphere the length of which is a charac-teristic linear size 119862
119899= 1205871198992
Γ((1198992) + 1) and Γ(119909) is agamma-function
Of course the same is true for the 119899-dimensional cube (orhypercube)119860
119899 its surface area and its volume are GEQs and
a length of its edge is a characteristic linear dimensionProvided 119897min exists there are no infinitesimal increments
for both the surface area and volume of 119860119899or 119861119899 only
minimal variations possible for these quantities are the caseIn what follows we consider only the spatial systems
whose surface areas and volumes are GEQsLet us consider a simple but very important example of
gravity in horizon spacesGravity and thermodynamics of horizon spaces and their
interrelations are currently most actively studied [67ndash79] Letus consider a relatively simple illustrationmdashthe case of a staticspherically symmetric horizon in space-time the horizonbeing described by the metric

The horizon location will be given by a simple zero of thefunction 119891(119903) at the radius 119903 = 119886
This case is studied in detail by Padmanabhan in hisworks[67 78] and by the author of this paper in [80] We usethe notation system of [78] Let for simplicity the space bedenoted byH
It is known that for horizon spaces one can introduce thetemperature that can be identified with an analytic continua-tion to imaginary time In the case under consideration ([78]Equation (116))

Therewith the conditions 119891(119886) = 0 and 1198911015840(119886) = 0 must
be fulfilledThen at the horizon 119903 = 119886 Einsteinrsquos equations have the

to consider (25) in a new notation expressing 119886 in terms ofthe corresponding deformation parameter 120572 In what followswe omit the subscript in formula (17) of 120572
119909 where the context
implies which index is the case In particular here we use 120572
instead of 120572119886 Then we have

that is the Gaussian curvature 119870119886is a solution of Einstein
equations in this caseThen we examine different cases of thesolution (33) with due regard for considerations of formula(21)
(21) First let us assume that 119886 ≫ 119897min As according to(7) the radius 119886 is quantized we have 119886 = 119873
119886119897min with the
natural number 119873119886≫ 1 Then it is clear that the Gaussian
curvature119870119886= 1119886
2asymp 0 takes a (nonuniform) discrete series
of values close to zero and within the factor 11198972min this seriesrepresents inverse squares of natural numbers

Let us return to formulas (9) and (21) for 119897 = 119886 consider1003816100381610038161003816100381610038161003816((120575119886)

119886119897min (35)
where 120573 in this case contains the proportionality factor thatrelates 119897min and 119897
119875
Then according to (21) 119886plusmn1
is a measurable value of theradius 119903 following after 119886 and we have
(119886plusmn1)120574equiv 119886 plusmn ((120575119886)

(36)
But as 119873119886≫ 1 for sufficiently large 119873
119886and fixed 120574 the
bracketed expression in rhs (36) is close to 1

As a result the Gaussian curvature119870119886plusmn1

in the case under study is only slightly different from119870119886
And this is the case for sufficiently large values of 119873119886
for any value of the parameter 120574 and for 120574 = 1 as wellcorresponding to the absolute minimum of fluctuations asymp
119897min or more precisely to 120573119897min However as all the quantitiesof the length dimension are quantized and the factor 120573 is onthe order of 1 actually we have 120573 = 1
Because of this provided the minimal length is involved119897min (9) is read as
10038161003816100381610038161003816(120575119897)1
10038161003816100381610038161003816min= 119897min (40)
But according to (12) 119897min = 120585119897119875is on the order of
Planckrsquos length and it is clear that the fluctuation |(120575119897)1|min
corresponds to Planckrsquos energies and Planckrsquos scales TheGaussian curvature119870
119886 due to its smallness (119870
119886≪ 1 up to the
constant factor 119897minus2min) and smooth variations independent of 120574(formulas (36)ndash(39)) is insensitive to the differences betweenvarious values of 120574
Consequently for sufficiently small Gaussian curvature119870119886 we can take any parameter from the interval 0 lt 120574 le 1 as
120574It is obvious that the case 120574 = 1 that is |(120575119897)
1|min = 119897min
is associated with infinitely small variations 119889119886 of the radius119903 = 119886 in the Riemannian geometry
Since then119870119886is varying practically continuously in terms
of 119870119886up to the constant factor we can obtain the following
expression
119889 [119871 (119870119886)] = 119889 [119875 (119870

Here 120581 is on the order of 1Taking into consideration point (11) stating that in this
case models for different values of the parameter 120574 arecoincident by formula (40) for any 120574 we have

10038161003816100381610038161003816min= 119897min (46)
But in this case the Gaussian curvature119870119886is not a ldquosmall
valuerdquo continuously dependent on 119886 taking according to(39) a discrete series of values119870

119870119886plusmn2
Yet (25) similar to (32) (33) is valid in the semiclassical
approximation only that is at low energiesThen in accordance with the above arguments the
limiting transition to high energies (44) gives a discrete chainof equations or a single equation with a discrete set ofsolutions as follows

and so on Here Θ(119870119886) is some function that in the limiting
transition to low energies must reproduce the low-energyresult to a high degree of accuracy that is 119875(119870
119886) appears for
119886 ≫ 119897min from formula (33)
lim119870119886rarr0
Θ(119870119886) = 119875 (119870
119886) (48)
In general Θ(119870119886) may lack coincidence with the high-
energy limit of the momentum-energy tensor trace (if any)
lim119886rarr 119897min
119875 (119870119886) (49)
At the same timewhenwenaturally assume that the staticspherically-symmetric horizon space-time with the radiusof several Planckrsquos units (45) is nothing else but a microblack hole then the high-energy limit (49) is existing andthe replacement of Θ(119870
119886) by 119875(119870
119886) in rhs of the foregoing
equations is possible to give a hypothetical gravitationalequation for the event horizon micro black hole But aquestion arises for which values of the parameter 119886 (45) (or119870119886) is this valid and what is a minimal value of the parameter
120574 = 120574(119886) in this caseIn all the cases under study (21) and (22) the deforma-
tion parameter 120572119886(17) (120582
119886(18)) is within the constant factor
coincident with the Gaussian curvature 119870119886(resp radic119870
119886) that
is in essence continuous in the low-energy case and discretein the high-energy case
In this way the above-mentioned example shows thatdespite the absence of infinitesimal spatial-temporal incre-ments owing to the existence of 119897min and the essentialldquodiscretenessrdquo of a theory this discreteness at low energies isnot felt the theory being actually continuous The indicateddiscreteness is significant only in the case of high (Planckrsquos)energies
In [78] it is shown that the Einstein equation for horizonspaces in the differential formmay be written as a thermody-namic identity (the first principle of thermodynamics) ([78]formula (119))

where as noted above 119879 is temperature of the horizonsurface 119878 is corresponding entropy 119864 is internal energy and119881 is space volume
Note that because of the existing 119897min practically allquantities in (50) (except of 119879) represent GEQ Apparentlythe radius of a sphere 119903 = 119886 its volume 119881 and entropyrepresent such quantities

119875equal to a sphere with the
radius 119886Because of this there are no infinitesimal increments
of these quantities that is 119889119886 119889119881 119889119878 And provided 119897min isinvolved the Einstein equation for the above-mentioned casein the differential form (50) makes no sense and is uselessIf 119889119886 may be purely formerly replaced by 119897min then as thequantity 119897min is fixed it is obvious that ldquo119889119878rdquo and ldquo119889119881rdquo in (50)will be growing as 119886 and 119886
2 respectively And at low energiesthat is for large values of 119886 ≫ 119897min this naturally leads toinfinitely large rather than infinitesimal values
In a similar way it is easily seen that the ldquoEntropicApproach to Gravityrdquo [82] in the present formalism is invalidwithin the scope of the minimal length theory In fact theldquomain instrumentrdquo in [82] is a formula for the infinitesimalvariation 119889119873 in the bit numbers119873 on the holographic screenSwith the radius119877 andwith the surface area119860 ([82] formula(418))

119866ℎ119889119860 =
119889119860
1198972119875
(52)
As 119873 = 1198601198972
119875and 119860 represents GEQ it is clear that 119873 is
also GEQ and hence neither 119889119860 nor 119889119873makes sense
6 Advances in High Energy Physics
It is obvious that infinitesimal variations of the screensurface area 119889119860 are possible only in a continuous theoryinvolving no 119897min
When 119897min prop 119897119875is involved the minimal variation Δ119860 is
evidently associated with a minimal variation in the radius 119877
119877 997888rarr 119877 plusmn 119897min (53)
is dependent on 119877 and growing as 119877 for 119877 ≫ 119897min
Δplusmn119860 (119877) = (119860 (119877 plusmn 119897min) minus 119860 (119877)) prop (
plusmn2119877
119897min+ 1)
= plusmn2119873119877+ 1
(54)
where119873119877= 119877119897min as indicated above
But as noted above a minimal increment of the radius 119877equal to |Δmin119877| = 119897min prop 119897
119875corresponds only to the case
of maximal (Planckrsquos) energies or similarly to the parameter120574 = 1 in formula (21) However in [82] the considered lowenergies are far from the Planck energies and hence in thiscase in (21) 120574 lt 1 (53) and (54) are respectively replacedby

(56)
An increase of rhs in (56) with the growth of 119877 (oridentically of119873
119877) for 119877 ≫ 119897min is obvious
So if 119897min is involved formula (418) from [82] makes nosense similar to other formulae derived on its basis (419)(420) (422) (532)ndash(534) in [82] and similar to thederivation method for Einsteinrsquos equations proposed in thiswork
Proceeding from the principal parameters of this work120572119897(or 120582119897) the fact is obvious and is supported by formula (19)
given in this paper meaning that
120572minus1
119877sim 119860 (57)
That is small variations of 120572119877(low energies) result in large
variations of 120572minus1119877 as indicated by formula (54)
In fact we have no-go theoremsThe last statements concerning 119889119878 119889119873 may be explicitly
interpreted using the language of a quantum informationtheory as follows due to the existence of the minimal length119897min the minimal area 1198972min and volume 1198973min are also involvedand that means ldquoquantizationrdquo of the areas and volumes Asup to the known constants the ldquobit numberrdquo119873 from (52) andthe entropy 119878 from (51) are nothing else but
119878 =119860
41198972min 119873 =
119860
1198972min (58)
it is obvious that there is a ldquominimalmeasurerdquo for the ldquoamountof datardquo that may be referred to as ldquoone bitrdquo (or ldquoone qubitrdquo)
The statement that there is no such quantity as 119889119873 (andresp 119889119878) is equivalent to claiming the absence of 025 bit0001 bit and so on
This inference completely conforms to the Hooft-Susskind Holographic Principle (HP) [60ndash63] that includestwo main statements as follows
(a) All information contained in a particular spatialdomain is concentrated at the boundary of thisdomain
(b) A theory for the boundary of the spatial domainunder study should contain maximally one degree offreedom per Planckrsquos area 1198972
119875
In fact (but not explicitly) HP implicates the existence of119897min = 119897
119875 The existence of 119897min prop 119897
119875totally conforms to HP
providing its generalization Specifically without the loss ofgenerality 1198972
119875in point (b) may be replaced by 119897
2
minSo the principal inference of this work is as follows
provided the minimal length 119897min is involved its existencemust be taken into consideration not only at high but alsoat low energies both in a quantum theory and in gravityThis becomes apparent by rejection of the infinitesimalquantities associated with the spatial-temporal variations119889119909120583 In other words with the involvement of 119897min the
general relativity (GR) must be replaced by a (still unframed)minimal length gravitation theory that may be denoted asGrav119897min In their results GR and Grav119897min should be very closebut as regards their mathematical apparatus (instruments)these theories are absolutely different
Besides Grav119897min should offer a rather natural transitionfrom high to low energies
[119873119871asymp 1] 997888rarr [119873
119871≫ 1] (59)
and vice versa
[119873119871≫ 1] 997888rarr [119873
119871asymp 1] (60)
where 119873119871
is integer from formula (7) determining thecharacteristics scale of the lengths 119871 (energies 119864 sim 1119871 prop

that is the Gaussian curvature 119870119886is a solution of Einstein
equations in this caseThen we examine different cases of thesolution (33) with due regard for considerations of formula(21)
(21) First let us assume that 119886 ≫ 119897min As according to(7) the radius 119886 is quantized we have 119886 = 119873
119886119897min with the
natural number 119873119886≫ 1 Then it is clear that the Gaussian
curvature119870119886= 1119886
2asymp 0 takes a (nonuniform) discrete series
of values close to zero and within the factor 11198972min this seriesrepresents inverse squares of natural numbers

Let us return to formulas (9) and (21) for 119897 = 119886 consider1003816100381610038161003816100381610038161003816((120575119886)

where 120573 in this case contains the proportionality factor thatrelates 119897min and 119897
119875
Then according to (21) 119886plusmn1
is a measurable value of theradius 119903 following after 119886 and we have
(119886plusmn1)120574equiv 119886 plusmn ((120575119886)
120574)min
= 119886 plusmn 1205731198731minus120574

(36)
But as 119873119886≫ 1 for sufficiently large 119873
119886and fixed 120574 the
bracketed expression in rhs (36) is close to 1

As a result the Gaussian curvature119870119886plusmn1

in the case under study is only slightly different from119870119886
And this is the case for sufficiently large values of 119873119886
for any value of the parameter 120574 and for 120574 = 1 as wellcorresponding to the absolute minimum of fluctuations asymp
119897min or more precisely to 120573119897min However as all the quantitiesof the length dimension are quantized and the factor 120573 is onthe order of 1 actually we have 120573 = 1
Because of this provided the minimal length is involved119897min (9) is read as
10038161003816100381610038161003816(120575119897)1
10038161003816100381610038161003816min= 119897min (40)
But according to (12) 119897min = 120585119897119875is on the order of
Planckrsquos length and it is clear that the fluctuation |(120575119897)1|min
corresponds to Planckrsquos energies and Planckrsquos scales TheGaussian curvature119870
119886 due to its smallness (119870
119886≪ 1 up to the
constant factor 119897minus2min) and smooth variations independent of 120574(formulas (36)ndash(39)) is insensitive to the differences betweenvarious values of 120574
Consequently for sufficiently small Gaussian curvature119870119886 we can take any parameter from the interval 0 lt 120574 le 1 as
120574It is obvious that the case 120574 = 1 that is |(120575119897)
1|min = 119897min
is associated with infinitely small variations 119889119886 of the radius119903 = 119886 in the Riemannian geometry
Since then119870119886is varying practically continuously in terms
of 119870119886up to the constant factor we can obtain the following
expression
119889 [119871 (119870119886)] = 119889 [119875 (119870
119886)] (41)

But in fact as in this case the energies are low it is morecorrect to consider
119871 ((119870119886plusmn1
)120574)
minus 119871 (119870119886) = [119875 (119870

119886)] equiv 119865
120574[119875 (119870
119886)]
(43)
where 120574 lt 1 rather than (41)In view of the foregoing arguments (21) the difference
between (43) and (41) is insignificant and it is perfectlycorrect to use (41) instead of (43)
(22) Now we consider the opposite case or the transitionto the ultraviolet limit
119886 997888rarr 119897min = 120581119897min (44)
That is
119886 = 120581119897min (45)
Here 120581 is on the order of 1Taking into consideration point (11) stating that in this
case models for different values of the parameter 120574 arecoincident by formula (40) for any 120574 we have
100381610038161003816100381610038161003816(120575119897)120574

10038161003816100381610038161003816min= 119897min (46)
But in this case the Gaussian curvature119870119886is not a ldquosmall
valuerdquo continuously dependent on 119886 taking according to(39) a discrete series of values119870
119886 119870119886plusmn1
119870119886plusmn2
Yet (25) similar to (32) (33) is valid in the semiclassical
approximation only that is at low energiesThen in accordance with the above arguments the
limiting transition to high energies (44) gives a discrete chainof equations or a single equation with a discrete set ofsolutions as follows

and so on Here Θ(119870119886) is some function that in the limiting
transition to low energies must reproduce the low-energyresult to a high degree of accuracy that is 119875(119870
119886) appears for
119886 ≫ 119897min from formula (33)
lim119870119886rarr0
Θ(119870119886) = 119875 (119870
119886) (48)
In general Θ(119870119886) may lack coincidence with the high-
energy limit of the momentum-energy tensor trace (if any)
lim119886rarr 119897min
119875 (119870119886) (49)
At the same timewhenwenaturally assume that the staticspherically-symmetric horizon space-time with the radiusof several Planckrsquos units (45) is nothing else but a microblack hole then the high-energy limit (49) is existing andthe replacement of Θ(119870
119886) by 119875(119870
119886) in rhs of the foregoing
equations is possible to give a hypothetical gravitationalequation for the event horizon micro black hole But aquestion arises for which values of the parameter 119886 (45) (or119870119886) is this valid and what is a minimal value of the parameter
120574 = 120574(119886) in this caseIn all the cases under study (21) and (22) the deforma-
tion parameter 120572119886(17) (120582
119886(18)) is within the constant factor
coincident with the Gaussian curvature 119870119886(resp radic119870
119886) that
is in essence continuous in the low-energy case and discretein the high-energy case
In this way the above-mentioned example shows thatdespite the absence of infinitesimal spatial-temporal incre-ments owing to the existence of 119897min and the essentialldquodiscretenessrdquo of a theory this discreteness at low energies isnot felt the theory being actually continuous The indicateddiscreteness is significant only in the case of high (Planckrsquos)energies
In [78] it is shown that the Einstein equation for horizonspaces in the differential formmay be written as a thermody-namic identity (the first principle of thermodynamics) ([78]formula (119))

where as noted above 119879 is temperature of the horizonsurface 119878 is corresponding entropy 119864 is internal energy and119881 is space volume
Note that because of the existing 119897min practically allquantities in (50) (except of 119879) represent GEQ Apparentlythe radius of a sphere 119903 = 119886 its volume 119881 and entropyrepresent such quantities

radius 119886Because of this there are no infinitesimal increments
of these quantities that is 119889119886 119889119881 119889119878 And provided 119897min isinvolved the Einstein equation for the above-mentioned casein the differential form (50) makes no sense and is uselessIf 119889119886 may be purely formerly replaced by 119897min then as thequantity 119897min is fixed it is obvious that ldquo119889119878rdquo and ldquo119889119881rdquo in (50)will be growing as 119886 and 119886
2 respectively And at low energiesthat is for large values of 119886 ≫ 119897min this naturally leads toinfinitely large rather than infinitesimal values
In a similar way it is easily seen that the ldquoEntropicApproach to Gravityrdquo [82] in the present formalism is invalidwithin the scope of the minimal length theory In fact theldquomain instrumentrdquo in [82] is a formula for the infinitesimalvariation 119889119873 in the bit numbers119873 on the holographic screenSwith the radius119877 andwith the surface area119860 ([82] formula(418))

(52)
As 119873 = 1198601198972
119875and 119860 represents GEQ it is clear that 119873 is
also GEQ and hence neither 119889119860 nor 119889119873makes sense

It is obvious that infinitesimal variations of the screensurface area 119889119860 are possible only in a continuous theoryinvolving no 119897min
When 119897min prop 119897119875is involved the minimal variation Δ119860 is
evidently associated with a minimal variation in the radius 119877
119877 997888rarr 119877 plusmn 119897min (53)
is dependent on 119877 and growing as 119877 for 119877 ≫ 119897min

(54)
where119873119877= 119877119897min as indicated above
But as noted above a minimal increment of the radius 119877equal to |Δmin119877| = 119897min prop 119897
119875corresponds only to the case
of maximal (Planckrsquos) energies or similarly to the parameter120574 = 1 in formula (21) However in [82] the considered lowenergies are far from the Planck energies and hence in thiscase in (21) 120574 lt 1 (53) and (54) are respectively replacedby

An increase of rhs in (56) with the growth of 119877 (oridentically of119873
119877) for 119877 ≫ 119897min is obvious
So if 119897min is involved formula (418) from [82] makes nosense similar to other formulae derived on its basis (419)(420) (422) (532)ndash(534) in [82] and similar to thederivation method for Einsteinrsquos equations proposed in thiswork
Proceeding from the principal parameters of this work120572119897(or 120582119897) the fact is obvious and is supported by formula (19)
given in this paper meaning that
120572minus1
119877sim 119860 (57)
That is small variations of 120572119877(low energies) result in large
variations of 120572minus1119877 as indicated by formula (54)
In fact we have no-go theoremsThe last statements concerning 119889119878 119889119873 may be explicitly
interpreted using the language of a quantum informationtheory as follows due to the existence of the minimal length119897min the minimal area 1198972min and volume 1198973min are also involvedand that means ldquoquantizationrdquo of the areas and volumes Asup to the known constants the ldquobit numberrdquo119873 from (52) andthe entropy 119878 from (51) are nothing else but
119878 =119860
41198972min 119873 =
119860
1198972min (58)
it is obvious that there is a ldquominimalmeasurerdquo for the ldquoamountof datardquo that may be referred to as ldquoone bitrdquo (or ldquoone qubitrdquo)
The statement that there is no such quantity as 119889119873 (andresp 119889119878) is equivalent to claiming the absence of 025 bit0001 bit and so on
This inference completely conforms to the Hooft-Susskind Holographic Principle (HP) [60ndash63] that includestwo main statements as follows
(a) All information contained in a particular spatialdomain is concentrated at the boundary of thisdomain
(b) A theory for the boundary of the spatial domainunder study should contain maximally one degree offreedom per Planckrsquos area 1198972
119875
In fact (but not explicitly) HP implicates the existence of119897min = 119897
119875 The existence of 119897min prop 119897
119875totally conforms to HP
providing its generalization Specifically without the loss ofgenerality 1198972
119875in point (b) may be replaced by 119897

minSo the principal inference of this work is as follows
provided the minimal length 119897min is involved its existencemust be taken into consideration not only at high but alsoat low energies both in a quantum theory and in gravityThis becomes apparent by rejection of the infinitesimalquantities associated with the spatial-temporal variations119889119909120583 In other words with the involvement of 119897min the
general relativity (GR) must be replaced by a (still unframed)minimal length gravitation theory that may be denoted asGrav119897min In their results GR and Grav119897min should be very closebut as regards their mathematical apparatus (instruments)these theories are absolutely different
Besides Grav119897min should offer a rather natural transitionfrom high to low energies

But in fact as in this case the energies are low it is morecorrect to consider
119871 ((119870119886plusmn1
)120574)
minus 119871 (119870119886) = [119875 (119870
119886plusmn1)120574] minus [119875 (119870
119886)] equiv 119865
120574[119875 (119870
119886)]
(43)
where 120574 lt 1 rather than (41)In view of the foregoing arguments (21) the difference
between (43) and (41) is insignificant and it is perfectlycorrect to use (41) instead of (43)
(22) Now we consider the opposite case or the transitionto the ultraviolet limit
119886 997888rarr 119897min = 120581119897min (44)
That is
119886 = 120581119897min (45)
Here 120581 is on the order of 1Taking into consideration point (11) stating that in this
case models for different values of the parameter 120574 arecoincident by formula (40) for any 120574 we have
100381610038161003816100381610038161003816(120575119897)120574

10038161003816100381610038161003816min= 119897min (46)
But in this case the Gaussian curvature119870119886is not a ldquosmall
valuerdquo continuously dependent on 119886 taking according to(39) a discrete series of values119870
119886 119870119886plusmn1
119870119886plusmn2
Yet (25) similar to (32) (33) is valid in the semiclassical
approximation only that is at low energiesThen in accordance with the above arguments the
limiting transition to high energies (44) gives a discrete chainof equations or a single equation with a discrete set ofsolutions as follows

(47)
and so on Here Θ(119870119886) is some function that in the limiting
transition to low energies must reproduce the low-energyresult to a high degree of accuracy that is 119875(119870
119886) appears for
119886 ≫ 119897min from formula (33)
lim119870119886rarr0
Θ(119870119886) = 119875 (119870
119886) (48)
In general Θ(119870119886) may lack coincidence with the high-
energy limit of the momentum-energy tensor trace (if any)
lim119886rarr 119897min
119875 (119870119886) (49)
At the same timewhenwenaturally assume that the staticspherically-symmetric horizon space-time with the radiusof several Planckrsquos units (45) is nothing else but a microblack hole then the high-energy limit (49) is existing andthe replacement of Θ(119870
119886) by 119875(119870
119886) in rhs of the foregoing
equations is possible to give a hypothetical gravitationalequation for the event horizon micro black hole But aquestion arises for which values of the parameter 119886 (45) (or119870119886) is this valid and what is a minimal value of the parameter
120574 = 120574(119886) in this caseIn all the cases under study (21) and (22) the deforma-
tion parameter 120572119886(17) (120582
119886(18)) is within the constant factor
coincident with the Gaussian curvature 119870119886(resp radic119870
119886) that
is in essence continuous in the low-energy case and discretein the high-energy case
In this way the above-mentioned example shows thatdespite the absence of infinitesimal spatial-temporal incre-ments owing to the existence of 119897min and the essentialldquodiscretenessrdquo of a theory this discreteness at low energies isnot felt the theory being actually continuous The indicateddiscreteness is significant only in the case of high (Planckrsquos)energies
In [78] it is shown that the Einstein equation for horizonspaces in the differential formmay be written as a thermody-namic identity (the first principle of thermodynamics) ([78]formula (119))

where as noted above 119879 is temperature of the horizonsurface 119878 is corresponding entropy 119864 is internal energy and119881 is space volume
Note that because of the existing 119897min practically allquantities in (50) (except of 119879) represent GEQ Apparentlythe radius of a sphere 119903 = 119886 its volume 119881 and entropyrepresent such quantities

within the constant factor 141198972
119875equal to a sphere with the
radius 119886Because of this there are no infinitesimal increments
of these quantities that is 119889119886 119889119881 119889119878 And provided 119897min isinvolved the Einstein equation for the above-mentioned casein the differential form (50) makes no sense and is uselessIf 119889119886 may be purely formerly replaced by 119897min then as thequantity 119897min is fixed it is obvious that ldquo119889119878rdquo and ldquo119889119881rdquo in (50)will be growing as 119886 and 119886
2 respectively And at low energiesthat is for large values of 119886 ≫ 119897min this naturally leads toinfinitely large rather than infinitesimal values
In a similar way it is easily seen that the ldquoEntropicApproach to Gravityrdquo [82] in the present formalism is invalidwithin the scope of the minimal length theory In fact theldquomain instrumentrdquo in [82] is a formula for the infinitesimalvariation 119889119873 in the bit numbers119873 on the holographic screenSwith the radius119877 andwith the surface area119860 ([82] formula(418))

119866ℎ119889119860 =
119889119860
1198972119875
(52)
As 119873 = 1198601198972
119875and 119860 represents GEQ it is clear that 119873 is
also GEQ and hence neither 119889119860 nor 119889119873makes sense

It is obvious that infinitesimal variations of the screensurface area 119889119860 are possible only in a continuous theoryinvolving no 119897min
When 119897min prop 119897119875is involved the minimal variation Δ119860 is
evidently associated with a minimal variation in the radius 119877
119877 997888rarr 119877 plusmn 119897min (53)
is dependent on 119877 and growing as 119877 for 119877 ≫ 119897min

(54)
where119873119877= 119877119897min as indicated above
But as noted above a minimal increment of the radius 119877equal to |Δmin119877| = 119897min prop 119897
119875corresponds only to the case

An increase of rhs in (56) with the growth of 119877 (oridentically of119873

It is obvious that infinitesimal variations of the screensurface area 119889119860 are possible only in a continuous theoryinvolving no 119897min
When 119897min prop 119897119875is involved the minimal variation Δ119860 is
evidently associated with a minimal variation in the radius 119877
119877 997888rarr 119877 plusmn 119897min (53)

(54)
where119873119877= 119877119897min as indicated above
But as noted above a minimal increment of the radius 119877equal to |Δmin119877| = 119897min prop 119897
119875corresponds only to the case
of maximal (Planckrsquos) energies or similarly to the parameter120574 = 1 in formula (21) However in [82] the considered lowenergies are far from the Planck energies and hence in thiscase in (21) 120574 lt 1 (53) and (54) are respectively replacedby

An increase of rhs in (56) with the growth of 119877 (oridentically of119873
119877) for 119877 ≫ 119897min is obvious
So if 119897min is involved formula (418) from [82] makes nosense similar to other formulae derived on its basis (419)(420) (422) (532)ndash(534) in [82] and similar to thederivation method for Einsteinrsquos equations proposed in thiswork

That is small variations of 120572119877(low energies) result in large
variations of 120572minus1119877 as indicated by formula (54)
In fact we have no-go theoremsThe last statements concerning 119889119878 119889119873 may be explicitly
interpreted using the language of a quantum informationtheory as follows due to the existence of the minimal length119897min the minimal area 1198972min and volume 1198973min are also involvedand that means ldquoquantizationrdquo of the areas and volumes Asup to the known constants the ldquobit numberrdquo119873 from (52) andthe entropy 119878 from (51) are nothing else but
119878 =119860

1198972min (58)
it is obvious that there is a ldquominimalmeasurerdquo for the ldquoamountof datardquo that may be referred to as ldquoone bitrdquo (or ldquoone qubitrdquo)
The statement that there is no such quantity as 119889119873 (andresp 119889119878) is equivalent to claiming the absence of 025 bit0001 bit and so on
This inference completely conforms to the Hooft-Susskind Holographic Principle (HP) [60ndash63] that includestwo main statements as follows
(a) All information contained in a particular spatialdomain is concentrated at the boundary of thisdomain
