Automorphisms of the Quantum Cohomology of the Springer Resolution and Applications
Changzheng Li, Changjian Su, Rui Xiong
In this paper, we introduce quantum Demazure--Lusztig operators acting by ring automorphisms on the equivariant quantum cohomology of the Springer resolution. Our main application…
Effective good divisibility of rational homogeneous varieties
Haoqiang Hu, Changzheng Li, Zhaoyang Liu
We compute the effective good divisibility of a rational homogeneous variety, extending an earlier result for complex Grassmannians by Naldi and Occhetta. Non-existence of nonconst…
On Seidel representation in quantum K-theory of Grassmannians
Changzheng Li, Zhaoyang Liu, Jiayu Song +1
We provide a direct proof of Seidel representation in the quantum K-theory QK(Gr(k, n)) by studying projected Gromov-Witten varieties concretely. As applications, we give an altern…
W-translated Schubert divisors and transversal intersections
DongSeon Hwang, Hwayoung Lee, Jae-Hyouk Lee +1
We study the toric degeneration of Weyl group translated Schubert divisors of a partial flag variety of Lie type A via Gelfand-Cetlin polytopes. We propose a conjecture that Schube…
On the fundamental group of open Richardson varieties
Changzheng Li, Frank Sottile, Chi Zhang
We compute the fundamental group of an open Richardson variety in the manifold of complete flags that corresponds to a partial flag manifold. Rietsch showed that these log Calabi-Y…
On Frobenius-Perron Dimension
Changzheng Li, Ryan M. Shifler, Mingzhi Yang +1
We propose a notion of Frobenius-Perron dimension for certain free -modules of infinite rank and compute it for the -modules of finite dimensional complex r…
