Title: Coxeter combinatorics and spherical Schubert geometry

Speaker: Reuven Hodges Affiliation: University of Illinois Zoom: Contact Karen Yeats

Abstract:

This talk will introduce spherical elements in a finite Coxeter system. These spherical elements are a generalization of Coxeter elements, that conjecturally, for Weyl groups, index Schubert varieties in the flag variety G/B that are spherical for the action of a Levi subgroup.
