Chevalley formulae for the motivic Chern classes of Schubert cells and for the stable envelopes
Leonardo C. Mihalcea, Hiroshi Naruse, Changjian Su
We prove a Chevalley formula to multiply the motivic Chern classes of Schubert cells in a generalized flag manifold by the class of any line bundle . Our formu…
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…
From motivic Chern classes of Schubert cells to their Hirzebruch and CSM classes
Paolo Aluffi, Leonardo C. Mihalcea, Jörg Schürmann +1
The equivariant motivic Chern class of a Schubert cell in a `complete' flag manifold is an element in the equivariant K theory ring of to which one adjoins a formal par…
Hook formulae from Segre-MacPherson classes
Leonardo C. Mihalcea, Hiroshi Naruse, Changjian Su
Nakada's colored hook formula is a vast generalization of many important formulae in combinatorics, such as the classical hook length formula and the Peterson's formula for the num…
Geometric properties of the Kazhdan-Lusztig Schubert basis
Cristian Lenart, Changjian Su, Kirill Zainoulline +1
We study classes determined by the Kazhdan-Lusztig basis of the Hecke algebra in the -theory and hyperbolic cohomology theory of flag varieties. We first show that, in -theor…
Left Demazure-Lusztig operators on equivariant (quantum) cohomology and K theory
Leonardo C. Mihalcea, Hiroshi Naruse, Changjian Su
We study the Demazure-Lusztig operators induced by the left multiplication on partial flag manifolds . We prove that they generate the Chern-Schwartz-MacPherson classes of Sch…
