GROUND STATE ENERGY OF MANY-BODY FERMI SYSTEM BY USING FEENBERG PERTURBATION THEORYSREÆKO KILIÆ Received 13 July 1992In this paper we derive an expression of the ground state energy of N identical interacting fermions by using Brillouin-Wigner-Feenberg perturbation theory. It represents a generalization of the Gell-Mann-Brueckner formula which was obtained for dense electron gas. UDC 538.94
