报告人简介：
Prof David Kosower is a professor at IphT, Saclay, France. He is the receipient of the J. J. Sakurai prize for Theoretical Physics in 2014 and Galileo Galilei Medal in 2023. His main interests are in scattering amplitudes, their applications to QCD and collider physics, and also their applications to gravitational waves.
讲座摘要：
I describe how to construct bases of numerators that give rise to finite Feynman integrals. I'll discuss briefly a Landau-equations based approach, and focus primarily on an approach based on Newton polytopes. This classification of finite numerators is a first step to organizing integral bases by infrared properties, which may simplify expressions for scattering amplitudes.
