dc.description.abstractA nonperturbative method of Green function calculation is applied to the Falicov_Kimball model Hamiltonian. In an approximation to first order in the hopping matrix elements, self_consistent solutions for several thermal averages and correlation functions do not show abrupt phase changes as a function of temperature. This treatment suggests that the Coulomb correlation by itself is not the key ingredient to understanding valence transitions.en_US
