Abstract:
We develop a scheme for constructing chains of equations for the irreducible Green's functions. The structure of the equations allows going beyond the usual perturbation theory in solving specific problems. We obtain general relations that allow any correlation function to be expressed through solutions of an infinite chain of equations for the irreducible functions.
