We write down an explicit conjecture for the instanton partition functions in 4d$ \mathcal{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 $ \mathcal{W} $-algebras known as quasi-superconformal algebras, in agreement with a recent general proposal.
