Description
Magic relations are a class of integration-by-parts identities that are generated in a sector which does not itself appear in the identity. They are of particular interest because their presence causes several otherwise successful methods in the Feynman-integral computational pipeline to break down. In this talk, we present a first step toward a systematic characterisation of such identities. In particular we discuss methods and algorithms for detecting and computing magic relations, which we find are deeply connected to the critical point varieties produced by Feynman integrals.
