Algebraic approach to the indirect interaction problem

The construction of an indirect interaction operator for the particles of one physical subsystem via the quasiparticles of another subsystem consists of two steps: an automorphic mapping of the Hamiltonian defined in the Hilbert space of the problem under consideration and the averaging over the quasipartical degrees of freedom. Generalization of the automorphic mappings to the class of the homomorphic mappings is introduced here.
