On equivariant oriented cohomology of Bott-Samelson varieties
Hao Li, Changlong Zhong
For any Bott-Samelson resolution of the flag variety , and any torus equivariant oriented cohomology , we compute the restriction formu…
Stable bases of the Springer resolution and representation theory
Changjian Su, Changlong Zhong
In this note, we collect basic facts about Maulik and Okounkov's stable bases for the Springer resolution, focusing on their relations to representations of Lie algebras over compl…
On the K-theory stable bases of the Springer resolution
Changjian Su, Gufang Zhao, Changlong Zhong
Cohomological and K-theoretic stable bases originated from the study of quantum cohomology and quantum K-theory. Restriction formula for cohomological stable bases played an import…
Formal affine Demazure and Hecke algebras of Kac-Moody root systems
Baptiste Calmès, Kirill Zainoulline, Changlong Zhong
We define the formal affine Demazure algebra and formal affine Hecke algebra associated to a Kac-Moody root system. We prove the structure theorems of these algebras, hence, extend…
