Parent event:

Workshop on "Combinatorics, Resurgence and Algebraic Geometry in Quantum Field Theory" [3]

I will begin with an overview of work on Feynman residues, graph hypersurfaces and their point counts over finite fields. Afterwards I will discuss recent work with Erik Panzer on point counts modulo $p^n$ and their relationship with Mellin-Feynman integrals.
