Colloquium
Time: 14:30
Speaker: Jeremy Usatine (Brown) Title: "Gromov-Witten theory and invariants of matroids" Room: Zoom Abstract: 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.
