Abstract:
The path integral for the case of nonadditive action appeared in the some problems
of solid state physics and problems concerning the propagation of the radiation in
the random media is considered. The complimentary difficults in compare with the
case of additive action are discussed. For the treated Green function the Dyson type
integral equation in which vertex function is represented as the series of perturbation
theory is derived. In the one special case the exact solution is recieved and the nonunit
arity of this solution is discussed.
