Ali Assem MAHMOUD - On the enumerative structures in QFT
Channel: Institut des Hautes Études Scientifiques (IHÉS)
Date: 29/11/2020

The aim of this talk is to display some enumerative results that are directly applied in quantum field theory. We shall see how the number of connected chord diagrams can be used to count one-particle-irreducible (1PI) diagrams in Yukawa theory. This translation of Feynman diagrams simplified the process of calculating the asymptotic behaviour of the corresponding Green functions.
