Recursion relations for two-loop self-energy diagrams on-shell
J. Fleischer, M. Yu. Kalmykov, A. V. Kotikov
A set of recurrence relations for on-shell two-loop self-energy diagrams with one mass is presented, which allows to reduce the diagrams with arbitrary indices (powers of scalar pr…

Manifestation of metric renormalization in quantum --gravity
M. Yu. Kalmykov
The renormalization group method in -gravity without matter fields is discussed. A criterion for the existence of the renormalization constant for the metric has been found, t…

The Background-Field Method and Noninvariant Renormalization
L. V. Avdeev, D. I. Kazakov, M. Yu. Kalmykov
We investigate the consistency of the background-field formalism when applying various regularizations and renormalization schemes. By an example of a two-dimensional model it…
