可以通过(量子)德林菲尔德-索科洛夫约简从仿射 sl(N) 代数构造一类一般的 β 代数,并通过 N 的分区进行分类。SU(N) 4D 规范理论中的表面算子也可以通过 N 的分区进行分类。我们认为,在存在表面算子的情况下,规范理论的瞬子配分函数也可以从相应的 β 代数计算出来。我们通过分析 Polyakov-Bershadsky 代数来测试这个建议,获得的结果与使用所谓的简单表面算子的 SU(3) 规范理论的已知配分函数一致。作为副产品,我们的建议暗示了 和 代数之间的关系。
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.
