Line operators in theories of class $\mathcal{S}$, quantized moduli space of flat connections, and Toda field theory

Ioana Coman, Maxime Gabella, Joerg Teschner

Non-perturbative aspects of $\mathcal{N}=2$ supersymmetric gauge theories of class $\mathcal{S}$ are deeply encoded in the algebra of functions on the moduli space $\mathcal{M}_\te…
