Abstract

Let TRT_R be a right nn-tilting module over an arbitrary associative ring RR. In this paper we prove that there exists a nn-tilting module TRT'_R equivalent to TRT_R which induces a derived equivalence between the unbounded derived category \D(R)\D(R) and a triangulated subcategory E\mathcal E_{\perp} of \D(\End(T))\D(\End(T')) equivalent to the quotient category of \D(\End(T))\D(\End(T')) modulo the kernel of the total left derived functor SLT-\otimes^{\mathbb L}_{S'}T'. In case TRT_R is a classical nn-tilting module, we get again the Cline-Parshall-Scott and Happel's results.
