Abstract
It is investigated what asymptotic behaviour of the vertex part of the fermion-fermion interaction is compatible with Lehmann's spectral representation for the one-body propagator. In contrast to the results of Abrikosov et al., it is shown that no term may be neglected in the equation for the vertex part.Keywords
