Degrees of freedom in the conventional QFT are effective.
The search of fundamental degrees of freedom is an important problem in physics.
Physical degrees of freedom
Physical degrees of freedom
Cohomologies of certain differential Q
What is called by cohomologies?
Fundamental Theory
11-dSUGRA ?
10-d SYM
2-d gauge model
Witten’s OSFT-like theoryor Chern-Simons-like theory
The Basis of Construction
odd variables
even variables The ring of polynomials
The ideal of constraints
The differential QB
This operator is nilpotent due to the constraints
Definition of fields
Calculation of effective action
The Systems of Quadratic Constraints
Allquadrics
Regular Singular
Chern-Simons theory
There are many such quadrics
Yang-Mills, SUGRA,2-d gauge model
There is a small number of such quadrics
The space of effective theories
