UBC Algebra and Algebraic Geometry Seminar: Kai Behrend
John Pardon has recently proved the Gromov-Witten Donaldson-Thomas correspondence using a new homology/cohomology machinery for 1-cycles in 3-folds. We study a much simplified version, namely for 0-cycles (points) in curves. In this case the theory...

Abstract: I will talk on joint work in progress with Behrang Noohi. We study the GIT problem given by the differential graded Lie algebra of Hochschild cochains of a finite graded algebra. This will lead to a definition of stability for non...

CRM - Fields - PIMS Prize Lecture: Kai Behrend
Motivated by subtle questions in Donaldson-Thomas theory, we study the spectrum of the inertia operator on the Grothendieck module of algebraic stacks. We hope to give an idea of what this statement means. Along the way, we encounter some elementary...
