Abstract
We study an extended version of the Anderson lattice model including t he local repulsion between itinerant and correlated f-like electrons ( the so-called Falicov-Kimball term). We investigate the role played by this interaction on the structure of the density of states and on the valence transition associated with the f-electron occupation, in the case of half filling.
