Dirac cohomology for symplectic reflection algebras

D Ciubotaru - Selecta Mathematica, 2016 - Springer
We define uniformly the notions of Dirac operators and Dirac cohomology in the framework
of the Hecke algebras introduced by Drinfeld (Anal i Prilozhen 20 (1): 69–70, 1986). We …

Spin Representations of Finite Coxeter Groups and Generalisations of Saxl's Conjecture

Y Chen, F Gu, W Osborne - arXiv preprint arXiv:2409.17540, 2024 - arxiv.org
This paper presents a natural generalisation of Saxl conjecture from a Lie-theoretical
perspective, which is verified for the exceptional types. For classical types, progress is made …

[图书][B] Extensions of graded affine Hecke algebra modules

KY Chan - 2014 - search.proquest.com
In this dissertation, we study extensions of graded affine Hecke algebra modules. In
particular, based on an explicit projective resolution on graded affine Hecke algebra …

[HTML][HTML] A vanishing theorem for Dirac cohomology of standard modules

KY Chan - Advances in Mathematics, 2018 - Elsevier
This paper studies the Dirac cohomology of standard modules in the setting of graded
Hecke algebras with geometric parameters. We prove that the Dirac cohomology of a …

On a twisted Euler-Poincar\'e pairing for graded affine Hecke algebras

KY Chan - arXiv preprint arXiv:1407.0956, 2014 - arxiv.org
We study a twisted Euler-Poincar\'e pairing for graded affine Hecke algebras, and give a
precise connection to the twisted elliptic pairing of Weyl groups defined by Ciubotaru-He …
