     To +nd out what an Adi polytope is we need to understand what a

    !easure and a si!plex is$ This is beause an Adi polytope is a

    !easure with so!e ri,ht si!plexes ta-en away .ro! it$

     There is an Adi polytope in every di!ension that is 2 or above$ This

    is beause there are no ri,ht si!plexes in less than 2 di!ensional

    spae$ It does ,et on.usin, beause the 2nd di!ensional Adi

    Polytope is a one di!ensional line$

    An explination o. the notation used"

    where xy/ are the axis in spae$

    The Quartic Polynomial, The Quintic Polynomial And Its Unsolvability

     _____________________________________________________________________ 

    Written By Adi Cox

    11th May 2015

    It is intriguing to learn that the quintic polynomial is not alwayssolvable by radicals. So I have looked into the structure ofpolynomials to see what I can find:

     _____________________________________________________________________ 

    Quartic Polynomial

     _____________________________________________________________________ 

    Ax^4 + Bx^3 + Cx^2 + Dx^1 + Ex^0 = 0

    A = 1B = a+b+c+dC = ab+ac+ad+bc+bd+cd

    D = abc+abd+acd+bcdE = abcd

    where {-a,-b,-c,-d} are the four solutions to the quartic polynomial.

      i  |  |  |  -1 ------------0------------ 1  |  |

      |  -i

    Example: where the solutions are: {-1, i, i, 1}

    we change the signs:{a=1, b=-i, c=-i, d=-1}

    A = 1

    B = (1)+(-i)+(-i)+(-1)  = -2i

    C = (1)(-i)+(1)(-i)+(1)(-1)+(-i)(-i)+(-i)(-1)+(-i)(-1)  = -i - i - 1 - 1 + i + i  = -2

    D = (1)(-i)(-i)+(1)(-i)(-1)+(1)(-i)(-1)+(-i)(-i)(-1)  = -1 + i + i + 1  = 2i

    E = (1)(-i)(-i)(-1)  = 1

  • 8/9/2019 Mathematics by Adi Cox

    17/27

    And so

      x^4 - 2ix^3 - 2x^2 + 2ix + 1 = 0

      => (x+1)(x-i)(x-i)(x-1)

     _____________________________________________________________________ 

    Quintic Polynomial

     _____________________________________________________________________ 

    Ax^5 + Bx^4 + Cx^3 + Dx^2 + Ex^1 + Fx^0 = 0

    A = 1B = a+b+c+d+eC = ab+ac+ad+ae+bc+bd+be+cd+ce+deD = abc+abd+abe+acd+ace+ade+bcd+bce+bde+cdeE = abcd+abce+abde+acde+bcdeF = abcde

    where {-a,-b,-c,-d,-e} are the five solutions to the quinticpolynomial.

      y= 1  ^  |  |  -1 --0----2--3----5----7--------11--> x  |  |

      y= -1

    Example: where the solutions are: {2, 3, 5, 7, 11}

    we change the signs:{a=-2, b=-3, c=-5, d=-7, e=-11}

    A = 1

    B = (-2)+(-3)+(-5)+(-7)+(-11)  = -28

    C = (-2)(-3)+(-2)(-5)+(-2)(-7)+(-2)(-11)+(-3)(-5)+(-3)(-7)+(-3)(-11)  +(-5)(-7)+(-5)(-11)+(-7)(-11)  = 6 + 10 + 14 + 22 + 15 + 21 + 33 + 35 + 55 + 77  = 288

    D = (-2)(-3)(-5)+(-2)(-3)(-7)+(-2)(-3)(-11)+(-2)(-5)(-7)  +(-2)(-5)(-11)+(-2)(-7)(-11)+(-3)(-5)(-7)+(-3)(-5)(-11)  +(-3)(-7)(-11)+(-5)(-7)(-11)  = - 30 - 42 - 66 - 70 - 110 - 154 - 105 - 165 - 231 - 385  = -1358

  • 8/9/2019 Mathematics by Adi Cox

    18/27

    E = (-2)(-3)(-5)(-7)+(-2)(-3)(-5)(-11)+(-2)(-3)(-7)(-11)  +(-2)(-5)(-7)(-11)+(-3)(-5)(-7)(-11)  = 210 + 330 + 462 + 770 + 1155  = 2927

    F = (-2)(-3)(-5)(-7)(-11)  = -2310

    And so

      x^5 - 28x^4 + 288x^3 - 1358x^2 + 2927x^1 - 2310x^0 = 0

      => (x-2)(x-3)(x-5)(x-7)(x-11)

     _____________________________________________________________________ 

      So What Happens With x^5 - x^1 + 1 = 0

    The above quintic polynomial is unsolvable by radicals, so let ussee what we get when we apply the previous methods for solvingpolynomials:

    Ax^5 + Bx^4 + Cx^3 + Dx^2 + Ex^1 + Fx^0 = 0

    A = 1B = a+b+c+d+e = 0C = ab+ac+ad+ae+bc+bd+be+cd+ce+de = 0D = abc+abd+abe+acd+ace+ade+bcd+bce+bde+cde = 0E = abcd+abce+abde+acde+bcde = -1F = abcde = 1

    where {-a,-b,-c,-d,-e} are the five solutions to the quinticpolynomial.

      x^5 - x^1 + 1 = 0

    => 1x^5 - 1x^1 + 1x^0 = 0

    => (1)x^5 + (0)x^4 + (0)x^3 + (0)x^2 + (-1)x^1 + (1)x^0 = 0

    So the problem above is going to take some satisfying. Nothing shortof inventing a new type of number with specific properties tosatisfy this puzzle.

    I'M WORKING ON IT!

    A

    Algebraic numberAny number that is the root of a non-zero polynomial with rationalcoefficients is an algebraic number.

    AmicableThe smallest pair of amicable numbers is (220, 284); for the proper

    divisors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55 and 110, ofwhich the sum is 284; and the proper divisors of 284 are 1, 2, 4, 71and 142, of which the sum is 220.{(220, 284), (1184, 1210), (2620, 2924), (5020, 5564), (6232, 6368), ...}

    C
