Title: Gromov-Witten theory and invariants of matroids
Date: Monday, January 30, 2023

Matroids are versatile combinatorial objects with deep connections to many subjects, including chromatic polynomials of graphs, arrangements of vectors and hyperplanes, and the geometry of Grassmannians. I will discuss joint work with Dhruv Ranganathan in which we use Gromov-Witten theory to associate new invariants to matroids, and I will explain how these new invariants are related to counting curves in certain geometric spaces.
