Gauge theory in low dimensions

Tuesdays 2:10–3:30pm, 732 Evans

Topic

We will study Lie group actions on categories and possibly higher categories, describing a mathematical approach to low-dimensional gauge theory. One goal may be to understand what 3-dimensional mirror symmetry wants to accomplish.

References will be updated.
