我们写下了4d$\数学{N}=2$SU(N)规范理论中存在某类曲面算子的瞬子配分函数的一个显式猜想。这些表面运算符通过N个分区来分类,并且对于每个分区都有一个关联的分区函数。对于划分N=N,我们恢复了Nekrasov形式,当N=1+…时+1我们复制了Feigin et的结果。艾尔对于N=1+(N−1)的情形,我们的表达式与限制SU(N)×SU(N)瞬子配分函数的另一种表述是一致的。当N=1+…时+1+2配分函数也可以从被称为拟超共形代数的某些$\数学{W}$-代数微扰地得到,这与最近的一个一般建议是一致的。
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.
