QG seminar: Opers - What They Are and What They are Good For

QG guest seminar.
Speaker: Peter Koroteev (UC Berkeley).
Title: "Opers - What They Are and What They are Good For".

I will introduce the space of (q-)opers on a projective line for a Lie group G. Then I will explain how this space is related to previously known results in geometry, physics, and integrable systems.
