Combinatorics Seminar

Degeneracy Loci and Back-stable Schubert Polynomials
Friday, December 3, 2021
3:00-4:00 PM
4088 East Hall Map

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. Speaker(s): Bill Fulton (University of Michigan)
