Dirac cohomology and simple modules of the Dunkl-Opdam subalgebra via inherited Drinfeld properties (1806.10862v2)
Published 28 Jun 2018 in math.RT
Abstract: In this paper we define a new presentation for the Dunkl-Opdam subalgebra of the rational Cherednik algebra. This shows that the Dunkl-Opdam subalgebra is a Drinfeld algebra. We use this fact to define Dirac cohomology for the DO subalgebra. We also formalise generalised graded Hecke algebras and define a Langlands classification to generalised graded Hecke algebras.
