Title: Compactifications and Degenerations
Date, Time, Location: Friday, Feb. 6th @3 – 4PM in Math Hall 520
Abstract: I will discuss a universal structure that appears in the compactification of spaces parametrizing points, maps, and vector bundles associated with a complex variety. It gives rise to numerous interesting correspondences between seemingly different geometries, shedding light on Hilbert schemes, Hurwitz spaces, and Gieseker moduli spaces of stable sheaves.
