Abstract

Ginzburg, Guay, Opdam and Rouquier established an equivalence of categories between a quotient category of the category O\mathcal{O} for the rational Cherednik algebra and the category of finite dimension modules of the Hecke algebra of a complex reflection group WW. We establish two generalizations of this result. On the one hand to the extension of the Hecke algebra associated to the normaliser of a reflection subgroup and on the other hand to the extension of the Hecke algebra by a lattice.
