The Isomorphism Problem for cominuscule Schubert Varieties
Edward Richmond, Mihail Tarigradschi, Weihong Xu
Cominuscule flag varieties generalize Grassmannians to other Lie types. Schubert varieties in cominuscule flag varieties are indexed by posets of roots labeled long/short. These la…

The isomorphism problem for Grassmannian Schubert varieties
Mihail Tarigradschi, Weihong Xu
We prove that Schubert varieties in potentially different Grassmannians are isomorphic as varieties if and only if their corresponding Young diagrams are identical up to a transpos…

Quantum K-theory of Incidence Varieties
Weihong Xu
We prove a conjecture of Buch and Mihalcea in the case of the incidence variety X=Fl(1,n-1;n) and determine the structure of its (T-equivariant) quantum K-theory ring. Our results…
