A general class of -algebras can be constructed from the affine sl(N) algebra by (quantum) Drinfeld–Sokolov reduction and are classified by partitions of N. Surface operators in an SU(N) 4D gauge theory are also classified by partitions of N. We argue that instanton partition functions of gauge theories in the presence of a surface operator can also be computed from the corresponding -algebra. We test this proposal by analysing the Polyakov–Bershadsky algebra obtaining results that are in agreement with the known partition functions for SU(3) gauge theories with a so-called simple surface operator. As a byproduct, our proposal implies relations between and algebras.
