Abstract: Bezrukavnikov and Etingof introduced some functors between the categories $ \mathcal {O}$ for rational Cherednik algebras. Namely, they defined two induction functors $ \mathrm {Ind}_b, \mathrm {ind}_\lambda $ and two restriction functors $ \mathrm {Res}_b,\mathrm {res}_\lambda $. They conjectured that one has functor isomorphisms $ \mathrm {Ind}_b\cong \mathrm {ind}_\lambda , \mathrm {Res}_b\cong \mathrm {res}_\lambda $. The goal of this paper is to prove this conjecture.
