内容介绍:Dirac cohomology for graded Hecke algebras is introduced by Barbasch-Ciubotaru-Trapa around 2010, as an analogue to the one for real reductive groups. In this talk, I shall discuss how to deform the Dirac cohomology in the setting of graded Hecke algebras. We then apply it to give a vanishing theorem for the Dirac cohomology of standard modules. If time permits, we also explain how to compute the Dirac cohomology of some non-unitary modules.
