Affine SL(2) Conformal Blocks from 4d Gauge Theories
We study Nekrasov's instanton partition function of four-dimensional N = 2 gauge theories in the presence of surface operators. This can be computed order by order in the instanton expansion by using results available in the mathematical literature. Focusing in the case of SU(2) quiver gauge th...
