Effective equidistribution in homogeneous spaces and restricted projection theorems

Abstract

Zoom Link

I will talk about recent developments on establishing effective versions of Ratner’s equidistribution theorem. I will explain the connection between quantitative behavior of unipotent orbits and problems from harmonic analysis on restricted projections. Then I will explain proofs for some important cases relying on arguments from incidence geometry. Based on joint work with Elon Lindenstrauss, Amir Mohammadi, and Zhiren Wang.
