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.
