HET Seminar | Feynman Integrals and Intersection Theory

Singularity structure of scattering amplitudes is as intricate as it is inscrutable. Work in this area over the recent years has been hinting at an existence of a “scalar product” between Feynman integrals, which would tell us how to characterize their analytic behavior. In this talk I will explain how to formulate this notion using the tools of intersection theory as well as review its theoretical and practical applications.
