Abstract

A system of kinetic equations describing the relaxation of electron and heavy quasy-particle excitations in the periodic Anderson Hamiltonian model is obtained. It is shown that a complete system of equations in the second and higher orders of perturbation theory in the spatially homogeneous case includes, in addition to kinetic equations for "light" and "heavy" quasi-particle, also a system of equations for the nonequilibrium spectrum of quasi-particles, the nonequilibrium renormalization parameter and the f-level of local electrons.
