Derived equivalences for trigonometric double affine Hecke algebras

Abstract

The trigonometric double affine Hecke algebra ${\mathbf{H}}_c$ for an irreducible root system depends on a family of complex parameters $c$ Given two families of parameters $c$ and $c^{\prime }$ which differ by integers, we construct the translation functor from ${\mathbf{H}}_c-Mod$ to ${\mathbf{H}}_{c^{\prime }}-Mod$ and prove that it induces equivalence of derived categories. This is a trigonometric counterpart of a theorem of Losev on the derived equivalences for rational Cherednik algebras.
