Description
Alday and Tachikawa have recently proposed a relation between conformal blocks in a two-dimensional theory with affine sl(2) symmetry and instanton partition functions in four-dimensional conformal N=2 SU(2) quiver gauge
theories in the presence of a certain surface operator. I will describe how to extend this proposal to a relation between conformal blocks in theories with affine sl(N) symmetry and instanton partition functions in conformal
N=2 SU(N) quiver gauge theories in the presence of a surface operator. I will also discuss the extension to non-conformal N=2 SU(N) theories.
