Abstract:
I will talk about the category of line operators of 4d $N=2^*$ theory. Using the formulation of Kapustin-Witten, it can be identified the category of B-branes of Hitchin moduli space over once-punctured torus with respect to a certain complex structure. I also explain the relations to geometric Satake, Mackay and Langlands correspondence.
