What is … a Feynman integral?

This page hosts information on Christian Bogner's talk "What is … a Feynman integral?" at the "What is …?" seminar. The talk will take place on Friday, February 10, 4pm (s.t.) at HU, RUD 25 1.023.

Abstract

Computations in perturbative Quantum Field Theory typically involve a certain kind of integral, the so-called Feynman integrals. Without assuming prior knowledge of particle physics, I will point out some of the main ideas on why we need these integrals and how they arise from certain graphs. In the end I will briefly point out some recently developed interrelations with modern mathematics.
