标题： Categorical 't Hooft expansion and chiral algebras

摘要： 扭曲全息理论捕捉了众所周知的全息对偶性的受保护方面。 我们展示了如何从与四维${\cal N}=2$超共形轮状规范理论相关的圈代数的't Hooft展开中系统地推导出全息对偶的B模型背景。 关键工具是在场论和世界面之间匹配平面BRST反常，尤其是在存在探测D膜的情况下。 我们的构造非常普遍，可以应用于没有四维起源的圈代数。 得到的全息对偶背景通常是非几何的，并且似乎是新颖的。 我们期望我们的策略在其他扭曲全息理论的例子，甚至可能在弱耦合全息理论中具有广泛的应用。 显示英文摘要

摘要： Twisted holography captures protected aspects of well-known holographic dualities. We show how the holographic dual B-model background can be systematically derived from the 't Hooft expansion of the chiral algebras associated to four-dimensional ${\cal N}=2$ superconformal quiver gauge theories. A crucial tool is the match of planar BRST anomalies in the field theory and on the worldsheet, especially in the presence of probe D-branes. Our construction is very general and can be applied to chiral algebras which do not have a four-dimensional origin. The resulting holographic dual backgrounds are typically non-geometric and appear to be novel. We expect our strategy to have a wide range of applications to other examples of twisted holography and, potentially, weak coupling holography.
