Algebraic Geometry and Combinatorics Seminar: Springer fibers, Richardson varieties, and Schubert calculus
Speaker: Martha Precup, Washington University in St. Louis
Abstract: In this talk, we will introduce two important subvarieties of the flag variety: Springer fibers and Richardson varieties. Both play central roles in the interplay between combinatorics, geometry, and representation theory. We will discuss recent results on their geometry, as well as open questions. This talk is based on joint work with Cristina Sabando Álvarez and with Steven Karp.
