Abstract

We expand the earlier introduced method of massive Feynman diagram calculation, namely, the differential equations method, to vertex-type diagrams. We show that this method provides a simple procedure of evaluating the result without D-space vertex- or propagator-type integrals (for the dimensional regularization) calculation.
