Kira
The content on this page was written by AI under human supervision.
The Kira page has moved to Kira, FireFly and Fermat; this address is kept so that older links still work. Kira is public software for integration-by-parts reduction, the linear-algebra step that rewrites the many Feynman integrals of a multi-loop calculation as combinations of a small set of master integrals, and it runs together with FireFly and Fermat. That page explains what these programs do and how BootLoops runs them, with worked examples and the full list of routines. It also documents the scripts BootLoops adds around Kira (parallel_kira_gen.py, parallel_kira_gen_uds.py, build_restage.py, ffsave_degree_census.py and the integral-weight codec pyred_weight.py), which live in tools/kira-stack/ in the BootLoops repository, released under the MIT license.
