During the Winter 2026 quarter, all of our meetings will be held in-person in 268 Skye Hall. This quarter, we'll have mostly-local speakers giving mostly-expositional talks close to the theme of "representation theory and character varieties."
Talks will run from 12:30-1:30pm unless otherwise indicated, but feel free to show up early for socializing with the speaker.
Current organizers: Peter Samuelson
