Crystal structure for representations of Cherednik algebras

Gordon, IG (Edinburgh)
Monday 23 March 2009, 10:00-11:00

Seminar Room 1, Newton Institute


I will report on recent work of Peng Shan (Paris VII). Using the parabolic induction and restriction functors of Bezrukavnikov and Etingof she showed the existence of a crystal structure on category O of the rational Cherednik algebras of type G(m,1,n) as n varies. Independently, Maurizio Martino (Bonn) and I proved the same result, with a slightly different construction which I shall outline.
