Multiplicities of singular points on Schubert varieties
Abstract: I will talk on the multiplicities of singular points on Schubert
varieties in the complete flag variety. We study the multiplicities
using degenerations of the Kazhdan-Lusztig ideals, and give a positive
combinatorial rule for the covexillary case. Then I will define drift
configurations and use them to compare multiplicities with
Kazhdan-Lusztig polynomials. This is joint work with Alex Yong.
