AI总结:

该研究在AdS/CFT框架下,利用热AdS$_3$中3维Chern-Simons引力的Wilson线算符构造$\mathfrak{sl}_3$环面共形块,并通过体张量技术与边界AGT对应算法验证了单点块的对偶构造。

摘要:

我们在AdS/CFT(反德西特/共形场论)框架下研究针对简并主场的$\mathcal{W}_3$环面共形块。在大中心荷极限下,$\mathcal{W}_3$代数退化为$\mathfrak{sl}_3$代数,$\mathfrak{sl}_3$块被定义为$\mathfrak{sl}_3$子代数生成元对$\mathcal{W}_3$块的贡献。我们考虑通过热AdS$_3$时空中3维Chern-Simons引力的Wilson线算符来构造$\mathfrak{sl}_3$环面块。根据对应关系,简并主场与作用于相应有限维$\mathfrak{sl}_3$表示的Wilson线算符相关联。我们利用体理论中的$\mathfrak{sl}_3$张量技术,以及边界CFT中基于AGT对应(Alday-Gaiotto-Tachikawa对应)的算法,验证了这种针对单点环面块的对偶构造。

英文摘要:

We study $\mathcal{W}_3$ toroidal conformal blocks for degenerate primary fields in AdS/CFT context. In the large central charge limit $\mathcal{W}_3$ algebra reduces to $\mathfrak{sl}_3$ algebra and $\mathfrak{sl}_3$ blocks are defined as contributions to $\mathcal{W}_3$ blocks coming from the generators of $\mathfrak{sl}_3$ subalgebra. We consider the construction of $\mathfrak{sl}_3$ toroidal blocks in terms of Wilson lines operators of $3d$ Chern-Simons gravity in the thermal AdS$_3$ space-time. According to the correspondence, degenerate primary fields are associated with Wilson lines operators acting in the corresponding finite-dimensional $\mathfrak{sl}_3$ representations. We verify this dual construction for one-point toroidal block using $\mathfrak{sl}_3$ tensor technique in the bulk theory and an algorithm based on AGT correspondence in the boundary CFT.
