The Geometry & Topology Student Seminar aims to provide a relaxed environment where students can practice giving talks and learn about geometry and topology from other grad students and postdocs. We meet on Monday's 11AM-12PM in JWB 333. Below is our schedule for Spring 2026 semester.

Fall semester:
February 18th: Minhua Cheng
Title: Introduction to Translation surfaces
February 23rd: Devanshi Merchant
Title: Mostow's Rigidity Theorem
Abstract: For surfaces, Gauss-Bonnet tells us that area is a topological invariant, but we can put many different metrics on it.
In higher dimensions, for a closed hyperbolic manifold, Mostow Rigidity tells us that, not only is the volume invariant, but there is only one metric up to isometry. In this talk, I will give you Gromov's proof of Mostow Rigidity for dimension 3.
March 2nd: Neelam
Title: Roller-Duality theorem for CAT(0) cube complexes
