Article Description

We write down an explicit conjecture for the instanton partition functions in 4d N = 2 SU(N) gauge theories in the presence of a certain type of surface operator. These surface operators are classified by partitions of N, and for each partition there is an associated partition function. For the partition N = N we recover the Nekrasov formalism, and when N = 1+... +1 we reproduce the result of Feigin et. al. For the case N = 1 + (N-1) our expression is consistent with an alternative formulation in terms of a restricted SU(N)×SU(N) instanton partition function. When N = 1+... +1+2 the partition functions can also be obtained perturbatively from certain W-algebras known as quasi-superconformal algebras, in agreement with a recent general proposal. © SISSA 2011.
