Green Family Lecture #2: Exploring Stability in Geometric and Functional Inequalities: OT and Beyond

Alessio Figalli
ETH Zurich

Geometric and functional inequalities have long been foundational in analysis, shaping our understanding of numerous mathematical and physical phenomena. Recently, attention has turned to questions of stability: if a function is nearly optimal in a known inequality, can we quantify just how close it is to a genuine minimizer? In this talk, I will discuss how Optimal Transport offers a potent framework for tackling these stability questions—while also noting scenarios where OT may not be the ideal tool...
