A Fermi liquid description of a periodic Anderson Ilamiltonian is presented byfollowing Luttinger. The Fermi surface sum rule is proved. It is shown that thespecific heat coefficient and the static spin susceptibility at the absolute zerotemperature are related with the expansion coefficients of the self-energy of felectrons. The expansion coefficients are estimated in the single-site approximationfor Coulomb correlation larger than the width of conduction bands.A possibility is pointed out that two or more than two conduction bands playa role in metallic valence fluctuating rare-earth compounds. The effective massof quasi-particles depends on the separation between conduction bands.
