Kazhdan-Lusztig polynomials and drift configurations
Li Li, Alexander Yong
The coefficients of the Kazhdan-Lusztig polynomials are nonnegative integers that are upper semicontinuous on Bruhat order. Conjecturally, the same properties hold for…

The direct sum map on Grassmannians and jeu de taquin for increasing tableaux
Hugh Thomas, Alexander Yong
The direct sum map Gr(a,n) x Gr(b,m) -> Gr(a+b,m+n) on Grassmannians induces a K-theory pullback that defines the splitting coefficients. We geometrically explain an identity from…

K-theoretic Schubert calculus for OG(n,2n+1) and jeu de taquin for shifted increasing tableaux
Edward Clifford, Hugh Thomas, Alexander Yong
We present a proof of a Littlewood-Richardson rule for the K-theory of odd orthogonal Grassmannians OG(n,2n+1), as conjectured in [Thomas-Yong '09]. Specifically, we prove that rec…
