Abstract
We present calculations of the electronic transport properties of heavy-fer mion systems within a semi-phenomenological approach to the dynamical mean field theory. In this approach the dynamics of the Hund's rules 4f(5f)-ioni c multiplet split in a crystalline environment is taken into account. Withi n the scope of this calculation we use the linear response theory to reprod uce qualitative features: of tile temperature-dependent resistivity and hal l conductivity, the magneto-resistivity and the thermoelectric power typica l for heavy-fermion systems. The model calculations are directly compared w ith experimental results on CeCu2Si2..
