Title

Deformations of local systems and the geometric Satake equivalence

Abstract

In this talk, I will discuss my joint work with Sam Raskin on the derived geometric Satake equivalence. As time permits, I will explain how this work has been applied in the proof of the geometric Langlands conjecture and in my work with Hayash. The main point is that when combined with local-to-global methods, my results with Raskin give information about deformations of reducible local systems on a compact Riemann surface.
