Query: Derivation of quantum theories:symmetries and the exact solution of the
  derived system   Based on the technique of derivation of a theory, presented in our recent
paper, we investigate the properties of the derived quantum system. We show
that the derived quantum system possesses the (nonanomalous) symmetries of the
original one, and prove that the exact Green functions of the derived theory
are expressed in terms of the semiclassically approximated Green functions of
the original theory.
