$\mathcal{N} \geqslant 2$超共形场论的手征代数讲座
Lectures on chiral algebras of $\mathcal{N} \geqslant 2$ superconformal field theories
摘要：
任何四维$\mathcal{N} \geqslant 2$超共形场论都有一个与二维手征代数\cite{Beem:2013sza}同构的受保护子扇区。这些讲座的目的是提供一个介绍的主题，包括手征代数的建设，四维物理的后果，以及最近的进展的简要总结。这是在冬季学校“YRISW 2020”上发表的讲座的记录，将出现在JPhysA的特刊上。
英文摘要：
Any four-dimensional $\mathcal{N} \geqslant 2$ superconformal field theory possess a protected subsector isomorphic to a two-dimensional chiral algebra \cite{Beem:2013sza}. The goal of these lectures is to provide an introduction to the subject, covering the construction of the chiral algebras, the consequences for four-dimensional physics, as well as a brief summary of recent progress. This is the writeup of the lectures given at the Winter School "YRISW 2020" to appear in a special issue of JPhysA.
