Derived equivalences of gerbey curves

Soumya Sankar (The Ohio State University)

Fri Jan 29, 20:00-21:00 (4 weeks ago)

Abstract: The question of whether derived equivalences determine a variety has been studied widely. Antieau, Krashen and Ward (AKW) studied the question of when two genus 1 curves are derived equivalent. A gerbey curve is a G_m gerbe over a usual curve. In joint work with Libby Taylor, we explore the question of when two gerbey genus 1 curves are derived equivalent. In this talk, I will give some background on derived equivalences of varieties, how they relate to derived equivalences of stacks and then talk about some extensions of the results of AKW.
