Circular quiver gauge theories, isomonodromic deformations and $W_N$\n fermions on the torus

We study the relation between class S theories on punctured tori and\nisomonodromic deformations of flat SL(N) connections on the two dimensional\ntorus with punctures. Turning on the self dual $\\Omega$-background corresponds\nto a deautonomization of the Seiberg-Witten integrable system which impl... View More
