Abstract

It has been shown some time ago that the Connes-Kreimer Hopf algebra encoding the combinatorics of perturbative renormalization applies also to some theories of tensorial fields. I will explain how this generalizes to combinatorially non-local interactions in general, how it can be used to compute amplitudes, and discuss an aspect where the algebraic structure might differ from usual local field theories.
