A quantum-field approach for describing many-particle Fermi systems at finitetemperatures and with spontaneously broken symmetry has been proposed. Ageneralized model of self-consistent field (SCF), which allows one to describethe states eligible for this system with various symmetries, is used as theinitial approximation. A perturbation theory has been developed, and a diagramtechnique for temperature Green's functions (GFs) has been constructed. TheDyson's equation for the self-energy and vertex parts has been deduced.
