Wee Math Seminar
About
What started as an informal meeting between postdocs and graduate students to chat about mathematics (in the Autumn of 2021 we talked about quivers and their representations, Grassmannians, Hilbert schemes, and other constructions in algebraic geometry) is now a wee bit more structured. You can send questions to Sam (about logistics) or Charlotte (about scheduling).
We meet on Fridays at 15:00 or 16:00, usually in room 110 or 311B.
