Computations with moduli of perverse point sheaves
Dan Abramovich, Jiun C. Chen
Given a birational modification of complex projective varieties with fiber dimension 1 and rational singularities, consider the main component of Bridgeland's moduli spac…

Flops, flips and perverse point sheaves on threefold stacks
Dan Abramovich, Jiun C. Chen
We consider two cases of birational transformations of Q-Gorenstein threefolds: the case of a terminal flop and the case of a Francia flip. In the first case we show that, if one r…

Flops and Equivalences of derived Categories for Threefolds with only Gorenstein Singularities
Jiun-Cheng Chen
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 transfor…
