Abstract:

I will describe joint work with Constantin Teleman, in which we cast topological eyes on a well-studied system in condensed matter physics. In particular, we use the symmetry in a strong form and apply the technology of extended topological field theory. We obtain a proof of duality, construct a new dual theory for models based on a nonabelian group, and make dynamical predictions. The lecture will not assume any physics background.
