Within the scope of this calculation using the linearized Boltzmann theory in the relaxation time approximation the qualitative features of the temperature-dependent resistivity, the magnetoresistivity and the thermoelectric power can be successfully reproduced; this is exemplified by a comparison with experimental results on CeCu_2Si_2.20 pages, RevTeX, 8 eps figures included, submitted to Phys.Rev.BStrongly Correlated Electronstext
