扭曲超引力与Koszul对偶:AdS $_3$中的一个个例研究

Twisted Supergravity and Koszul Duality: A case study in AdS$_3$

Kevin Costello, Natalie M. Paquette

摘要:

本文研究了AdS $_3\times S^3\times T^4$上的超引力与对称轨道理论$Sym^N(T^4)$(在其模空间上)的SCFT之间的全息对偶性的一个简化变体$N \rightarrow \infty$。这个变体是由第一作者和Si Li提出的一个扭曲而产生的。我们恢复了一些结果,直接在扭曲体理论的原始二元性工作的受保护的分区。此外,我们确定了扭曲引力理论的$N\rightarrow \infty$极限中出现的对称代数。我们强调$\textit{Koszul duality}$的作用--一个无处不在的数学概念,我们提供了一个友好的介绍--在场论和弦论。在说明了Koszul对偶的外观在“玩具”的例子全纯陈-西蒙斯理论,我们描述了如何(变形)Koszul对偶涉及散装和边界运营商在我们扭曲的设置,并解释如何可以计算代数OPEs图解使用这个概念。进一步的细节、结果和计算将在配套的论文中出现。

英文摘要:

In this note, we study a simplified variant of the familiar holographic duality between supergravity on AdS$_3\times S^3\times T^4$ and the SCFT (on the moduli space of) the symmetric orbifold theory $Sym^N(T^4)$ as $N \rightarrow \infty$. This variant arises conjecturally from a twist proposed by the first author and Si Li. We recover a number of results concerning protected subsectors of the original duality working directly in the twisted bulk theory. Moreover, we identify the symmetry algebra arising in the $N\rightarrow \infty$ limit of the twisted gravitational theory. We emphasize the role of $\textit{Koszul duality}$---a ubiquitous mathematical notion to which we provide a friendly introduction---in field theory and string theory. After illustrating the appearance of Koszul duality in the "toy" example of holomorphic Chern-Simons theory, we describe how (a deformation of) Koszul duality relates bulk and boundary operators in our twisted setup, and explain how one can compute algebra OPEs diagrammatically using this notion. Further details, results, and computations will appear in a companion paper.
