Pollitz gave a characterization of complete intersection rings in terms of the triangulated structure of their derived category, akin to the Auslander-Buchsbaum-Serre characterization of regular rings. In this talk, we will explore how to bring this characterization back to the world of modules, and discuss the role of cohomological support varieties in solving this problem.
This is joint work with Ben Briggs and Josh Pollitz.
This video is part of the New Directions in Group Theory and Triangulated Categories seminar series.
