Quantum Schubert calculus for smooth Schubert divisors of
Changzheng Li, Jiayu Song, Rui Xiong +1
The paper studies quantum Schubert calculus for smooth Schubert divisor varieties in the complete flag variety, giving a Borel-type presentation of their quantum cohomology and der…

An anticanonical perspective on G/P Schubert varieties
Changzheng Li, Konstanze Rietsch, Mingzhi Yang
We describe a natural basis of the Cartier class group of an arbitrary Schubert variety in a flag variety of general Lie type. We then characterise when the Schuber…

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…
