INITIAL

INitial InTegral ALgorithm: A package for obtaining the transformation matrix to a canonical basis from one Feynman integral of uniform transcendental weight.

This Mathematica package is based on the following publications:

  • Christoph Dlapa, Johannes Henn and Kai Yan, Deriving canonical differential equations for Feynman integrals from a single uniform weight integral, arxiv:2002.02340
  • Christoph Dlapa, Johannes M. Henn and Fabian Wagner, An algorithmic approach to finding canonical differential equations for elliptic Feynman integrals, arXiv:2211.16357

Installation

Written completely in Mathematica, this package requires no installation other than its dependencies:

This package relies on the FiniteFlow framework (see arXiv:1905.08019 for more information).
