Description

We present the set of tools for computations on Feynman diagrams. Various package modules implement: - graph manipulation, serialization, symmetries and automorphisms - calculators, which are used to calculate integrals by particular methods (analytical or numerical). - UV-counterterms calculation using IR-rearrangement and R* operation (minimal subtraction scheme) The following calculators are available out of the box: reduction to master integrals (using LiteRed IPB and DRR rules), sector decomposition and the Gegenbauer polynomial x-space technique. These set of calculators can be extended by creating your own Feynman diagrams calculators using API provided. Library implemented in python (>=2.6 compatibility) and uses GiNAC as computer algebra engine.
