We are a graduate-student run seminar showcasing special topics in geometry and topology at large. Talks in this seminar often involve
Differentiable/Riemannian geometry, analysis on manifolds, and metric spaces. There have also been talks in topological data analysis and sheaf theory.
Graduate students at all levels are welcome to participate. The graduate student seminars are opportunities to practice talks before a conference, or to
present something interesting to share among friends. After all, the best way to learn something is to teach it!
Spring 2025

We meet on Friday, 1:00 to 1:50 PM, in Altgeld Hall 241.
