Title:  Degeneracy Loci and Back-stable Schubert Polynomials

Abstract:   The notion of stability has motivated the search for Schubert polynomials in types A, B, C, and D. Recently in type A a notion of back-stability has been developed by Lam, Lee, and Shimozono. One can trace these ideas through the long history of finding formulas for degeneracy loci in algebraic geometry, which gives some insight and occasionally new formulas.

Anything new in this talk is joint work with Dave Anderson, and we hope it serves as an introduction to Dave's talk in this seminar next semester.
