Harvard-MIT Algebraic Geometry Seminar

Tuesday, September 08, 2020 at 3:00pm to 4:00pm

Virtual Event

Featured Speaker: Elden Elmanto (Harvard)

Title: Descent for semiorthogonal decompositions.

Abstract: This talk is an invitation to derived methods in algebraic geometry. We will use derived algebraic geometry to give a solution to the problem of descending "bases" (semiorthogonal decompositions) on the category of perfect complexes on algebraic varieties. This generalizes, and gives a uniform treatment of the work of Elagin, Shinder, Bernardara, Bergh-Schürer, Auel-Bernardara and Ballard-Duncan-McFaddin.

Based on joint work with Ben Antieau in ArXiv:1912.08970
