Computations with moduli of perverse point sheaves

Dan Abramovich, Jiun C. Chen

Given a birational modification $X \to Y$ 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…
