The Gorishny-Isaev vacuum integrations and UV(IR)-regime

Abstract

We present the further development of the vacuum massless integrations. In particular, in the Gorishny-Isaev formula, it has been shown that the delta function representing UV-regime should be treated within the sequential approach. It allows us to resolve the problem of vacuum integrations related to the analytical continuation of diagram indices.
