Combinatorics of Feynman integrals
Appears in collection : Algebraic combinatorics, resurgence, moulds and applications / Combinatoire algébrique, résurgence, moules et applications
Very recently, David Roberts and I have discovered wonderful conditions imposed on Feynman integrals by Betti and de Rham homology. In decoding the corresponding matrices, we encounter asymptotic expansions of a refined nature. In making sense of these, we appear to have some refuge in resurgence.
