In realistic problems, one encounters several types of generalized Kondo systems. Variational and self-consistent perturbational treatments are reviewed for the Tm-like and the Sm-like valence-fluctuating magnetic ions, the finite-U Anderson model and the two-impurity Anderson model as examples for such generalizations, and they are discussed from a unified standpoint.
