Dan Abramovich, Alexander Polishchuk
In this work more questions arise than answers given, for which of course we do not apologize. The core of this paper is concerned with the construction of a ``constant'' t-structu…

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…
