• The method of anomalous Green functions introduced by Takano and Ogawa into the Kondo problem of s-d interaction is reformulated more carefully. It is found that the self-consistency equation should contain the energy shift caused by the s-d interaction as a parameter and therefore can have a non-trivial solution even in the limit of vanishing anomalous Green functions. The equation in this limit has precisely the same form as Yoshimori's secular equation, provided that the most divergent corrections are included into the vertex part.
