Abstract
We exactly solve an extended version of the Anderson lattice model inc luding the local repulsion between itinerant and correlated f-like ele ctrons, under the assumption that hopping amplitudes are constant and unconstrained. We investigate the role played by the various interacti ons of the Hamiltonian on the valence transition associated with the f -electron occupation and on the behaviour of the density of doubly occ upied sites.
