Description
Differential equations for Feynman integrals appear both in the form of annihilating operators (as D-ideals) as well as in matrix form (as Pfaffian systems). In my talk I will relate both of them in the context of Weyl algebras and Gröbner bases. This is based on arXiv:2504.01362 which describes how to obtain Pfaffian systems from D-ideals. An implementation is provided in Macaulay2.
