Factorization in generalized Calogero-Moser spaces

Understand

Using a recent construction of Bezrukavnikov and Etingof we prove that there is a factorization of the Etingof-Ginzburg sheaf on the generalized Calogero-Moser space associated to a complex reflection group.

• In the case W = S_n, this confirms a conjecture of Etingof and Ginzburg.
