The Algebraic Geometry Seminar takes place on Wednesdays 3:30–4:30PM. Pre-talks (which graduate students are particularly encouraged to attend) take place Wednesdays 3:00–3:25PM.
The in-person talks will take place in STON 215. Some talks will be presented online via Zoom.
Please see below for the most up to date information. Here is the Zoom link for the online talks:

September 2: Laurentiu Maxim (University of Wisconsin, Madison)
Location: STON 215
Title: A conjectural characteristic-class version of the Hodge index theorem for singular complex algebraic varieties
Abstract: In this talk, I will discuss a conjectural characteristic-class version of the Hodge index theorem for singular complex algebraic varieties. This was formulated by Brasselet, Schuermann, and Yokura, expressing the Goresky-MacPherson topological L-classes in terms of suitable Hodge-theoretic L-classes. I will survey recent developments and results on spaces for which the conjecture has been proved. Based on joint work with M. Aligholi and J. Schuermann.

Title: Hodge theory of toric singularities
Abstract: Toric variety is a normal variety containing an algebraic torus as an open dense subset whose action on itself extends to the whole space. They provide a fruitful interplay between algebraic geometry and convex geometry since properties on one side (e.g. smoothness, compactness) can be translated into properties involving discrete objects (e.g. cones, fans, polytopes). I will talk about singularities of these varieties from a Hodge theoretic point of view, with applications towards local cohomology and singular cohomology, based on joint works with Sridhar Venkatesh.
