Algebraic Combinatorics Seminar - Reuven Hodges

TITLE: Coxeter combinatorics and spherical Schubert geometry

Speaker:
Reuven Hodges

Affiliation:

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.
