Application of conformal mapping and Padé approximants to the calculation of various two-loop Feynman diagrams
J. Fleischer, O. V. Tarasov
Feynman diagrams are calculated by means of their Taylor series expansion in terms of external momenta squared. It is demonstrated in various examples that by the application of co…

Calculation of Feynman Diagrams from their Small Momentum Expansion
J. Fleischer, O. V. Tarasov
A new powerful method to calculate Feynman diagrams is proposed. It consists in setting up a Taylor series expansion in the external momenta squared (in general multivariable). The…
