Flops and Equivalences of derived Categories for Threefolds with only Gorenstein Singularities
arXiv:math/0202005
Abstract
The main propose of this paper is to show that Bridgeland's moduli space of perverse point sheaves for certain flopping contractions gives the flops, and the Fourier-Mukai transform given by the birational correspondence of the flop is an equivalence between bounded derived categories.
