✦ Synopsis

Some rigorous results on the Falicov-Kimball model are reported which concern the low temperature states of the system for large values of the coupling constant. For this study a cluster expansion is introduced which can be used to investigate the effective interaction between the static particles.

## Abstract Finite‐temperature properties of the Falicov‐Kimball model on the square lattice have been studied in the perturbative regime, i.e. in the case: __t__ = __U__ ≪ 1, where __t__ is the hopping constant and __U__ denotes the Coulomb interaction strength. In our study, we have determined th
