Decoupling of chains of equations for two-time Green's functions
Yu. A. Tserkovnikov
Abstract:
A study is made of different methods of finding solutions of chains of equations for two-time
temperature-dependent Green's flmctions which enable one to find simple expressions for
the energy of elementary excitations and the damping. The proposed methods are illustrated
by the examples of the single-particle Green's function and the matrix Green's function employed in the theory of superfluidity and superconductivity.
