我总结和讨论了最近的一些结果制定行动的六维超共形场理论的语言使用高规范理论。后者保证了我们的结构的数学一致性,我们回顾了这个框架的关键方面,如L∞-代数和相应的运动学数据给出的更高的连接。然后,我们证明了自对偶弦方程存在一个数学上一致的非阿贝尔扩张,它满足许多物理期望。我们的构造倾向于一个特定的更高规范群,这使我们得到更高的主丛,称为弦结构。使用这些,我们设法制定了一个六维作用量,它与著名的(2,0)理论有许多相同的性质,但在某些关键点上仍然与它不同。
I summarize and discuss some recent results on formulating actions of six‐dimensional superconformal field theories using the language of higher gauge theory. The latter guarantees mathematical consistency of our constructions and we review crucial aspects of this framework, such as L∞ ‐algebras and corresponding kinematical data given by higher connections. We then show that there is a mathematically consistent non‐Abelian extension of the self‐dual string equation which satisfies many physical expectations. Our construction favors a particular higher gauge group leading us to higher principal bundles known as string structures. Using these, we manage to formulate a six‐dimensional action which shares many properties with the famous (2,0)‐theory but also still differs from it in some key points.
