QFT, EFT and GFT

Abstract: I will talk about an intriguing correspondence between 2-2 scattering in quantum field theory (QFT) and an area of mathematics called geometric function theory (GFT). The area of GFT that we will focus on is the theory of typically real, univalent functions which are the relevant objects to understand scattering amplitudes. This understanding relies heavily on a crossing symmetric dispersion relation for 2-2 scattering that was recently resurrected and furthered in the context of effective field theories (EFT). Time permitting, I will explain how to get the crossing symmetric EFT-hedron in effective field theories.
