Reduze 2: Distributed Feynman Integral Reduction
Reduze is a computer program for reducing Feynman integrals to master integrals employing a variant of Laporta's reduction algorithm.
This web page presents version 2 of the program. New features include the distributed reduction of single topologies on multiple processor cores. The parallel reduction of different topologies is supported via a modular, load balancing job system. Fast graph and matroid based algorithms allow for the identification of equivalent topologies and integrals. Reduze uses GiNaC or, optionally, Fermat to perform manipulations of algebraic expressions.
Version 2.4: fix bug in Symanzik polynomial based integral identification. Thanks to Stephen Jones.
Version 2.3: support scan for super-convergent integrals, fix some issues.
Version 2.2: support GiNaC 1.7, export to Loopedia, add example for finite integrals.
Version 2.1: change to basis of finite integrals, cut propagators, linear propagators and much more. We also fixed many bugs.
