Descripción
In general, Feynman integrals evaluate in terms of complicated transcendental numbers and functions, which arise from their underlying geometries. In this talk, I will first review the type of Feynman integrals that can occur in particle physics phenomenology and in the post-Minkowskian expansion for black-hole scattering. Then, using the methods of differential equations and leading singularities, I will introduce the new geometries appearing with each loop order, and the corresponding special functions that occur.
