MIT-Harvard-MSR Combinatorics Seminar

Friday, October 15, 2021 at 3:30pm to 4:30pm

Harvard Science Center 507, 10 Oxford Street, Cambridge, MA

Speaker:  Chris Eur (Harvard University)

Title:  Tautological classes of matroids


We introduce a new way of geometrically studying matroids that unifies, recovers, and extends several recent developments on the interaction between matroid theory and algebraic geometry. A key step that we establish is a formula relating Ehrhart polynomials of generalized permutohedra to their volumes in a way that is different from previous methods. Joint work with Andrew Berget, Hunter Spink, and Dennis Tseng.
