Address: 20 Garden Street, Cambridge 02138, United States

Speaker: Ahsan Khan (Harvard CMSA)

I will discuss how a certain (relative) Lie algebra cochain complex categorifies the Schur index of N=2 supersymmetric gauge theory. For the special case of Seiberg-Witten theory I will provide give a conjectured description of this cohomology.
