FeynGKZ: a Mathematica package for solving Feynman integrals using GKZ hypergeometric systems
B. Ananthanarayan, Sumit Banik, Souvik Bera +1
In the Lee-Pomeransky representation, Feynman integrals can be identified as a subset of Euler-Mellin integrals, which are known to satisfy Gel'fand-Kapranov-Zelevinsky (GKZ) syste…
