Richardson varieties and Poisson geometry
Speaker: Samuel Evens, University of Notre Dame
Abstract: I will discuss a Poisson structure on the flag variety of a complex semisimple Lie group with the property that its symplectic leaves are Richardson varieties, i.e., intersections between Schubert cells and opposite Schubert cells. This structure arises by taking a certain limit of the Bruhat-Poisson structure under a complex torus action. This talk is based on joint work with Arlo Caine.
