Stability conditions on crepant resolutions of quotients of product varieties
Alexander Perry, Saket Shah
We construct stability conditions on crepant resolutions of certain quotients of product varieties, giving as a special case the first examples of stability conditions on strict Ca…

The period-index conjecture for abelian threefolds and Donaldson-Thomas theory
James Hotchkiss, Alexander Perry
We prove the period-index conjecture for unramified Brauer classes on abelian threefolds. To do so, we develop a theory of reduced Donaldson-Thomas invariants for 3-dimensional Cal…
