Multimatroids and Rational Curves with Cyclic Action

Explore the fascinating intersection of multimatroids and moduli spaces of rational curves with cyclic action in this 50-minute mathematics lecture from the Geometry of Matroid Workshop. Delve into how multimatroids, which extend beyond traditional matroids and delta-matroids, emerge naturally from topological graph theory. Learn about a groundbreaking combinatorial formula that connects intersection numbers on moduli space to independence polytopal complex volumes of multimatroids. Based on collaborative research with Emily Clader, Chiara Damiolini, Chris Eur, Daoji Huang, and Rohini Ramadas, gain insights into this advanced mathematical exploration presented by Institute for Advanced Study researcher Shiyue Li.
