最近，Alday和Tachikawa [1]提出了具有仿射sl（2）对称性的二维共形理论中的共形块与具有某种表面算符的四维共形$ mathcal{N} = 2 $ SU（2）规范理论中的瞬子配分函数之间的关系.本文将这一建议推广到具有仿射sl（N）对称性的共形块理论与共形mathcal{N} = 2 $ SU（N）规范理论中的瞬子配分函数之间的关系。我们还讨论了非共形的mathcal{N} = 2 $ SU（N）理论的推广。
Recently Alday and Tachikawa [1] proposed a relation between conformal blocks in a two-dimensional theory with affine sl(2) symmetry and instanton partition functions in four-dimensional conformal $ mathcal{N} = 2 $ SU(2) quiver gauge theories in the presence of a certain surface operator. In this paper we extend this proposal to a relation between conformal blocks in theories with affine sl(N) symmetry and instanton partition functions in conformal $ mathcal{N} = 2 $ SU(N) quiver gauge theories in the presence of a surface operator. We also discuss the extension to non-conformal $ mathcal{N} = 2 $ SU(N) theories.
