Falicov-Kimball Models: A Partial Review of the Ground States Problem
(745K, 1 postscript file with 4 PS figures in one .tar file)

ABSTRACT.  In this review we present a biased review of the ground state properties 
of the Falicov-Kimball models in 1,2 and infinite dimensions considering 
either fermions or hard core bosons. In particular, we want to show the 
very rich structure that these models exhibit, and to point out the 
analogies and differences associated with the statistic and the 
nature of the lattice (bipartite or not). The flux phase problem is 
also discussed.
