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…
