摘要：

We present a general scheme for a construction of meanfield-like theories of itinerant lattice fermions based on solutions to the exact d = infinity grand canonical potential. The general construction is explicitly demonstrated on the exactly solvable d = infinity Falicov-Kimball model. A mean-field zero-temperature behaviour of this sample model is studied quantitatively.
