Renormalized system of equations for vertex functions of the chronological exponential

V. D. Gordevskii, V. A. Shcherbina


Abstract: One of the possible ways is proposed for removing the ultraviolet cutoffs in the renormalized systems of equations for the total contributions from the strongly connected Feynman diagrams (the so-called vertex functions) obtained in earlier work of the authors.
