Danhua Song, Kai Lou, Ke Wu, Jie Yang, Fuhao Zhang

摘要:

本文在高次规范理论的框架下研究高次杨-米尔斯理论。证明了用李群的交叉模代替群$U(1)$,可以将2-形式电磁学推广到2-形式Yang-Mills理论.为了将这一理论推广到更高的结构,我们发展了一个3-形式的具有李群2-交叉模的Yang-Mills理论。首先,我们给出了李代数2-交叉模上的非退化对称$G$ -不变形式的一个显式构造。然后,我们得到了3-曲率的3-Bianchi-恒等式。最后,我们构造了一个3-形式的Yang-Mills作用量,并得到了相应的场方程。

英文摘要:

In this paper, we study the higher Yang-Mills theory in the framework of higher gauge theory. It was shown that the 2-form electromagnetism can be generalized to the 2-form Yang-Mills theory with the group $U(1)$ replaced by a crossed module of Lie groups. To extend this theory to even higher structure, we develop a 3-form Yang-Mills theory with a 2-crossed module of Lie groups. First, we give an explicit construction of non-degenerate symmetric $G$-invariant forms on the 2-crossed module of Lie algebras. Then, we derive the 3-Bianchi-Identities for 3-curvatures. Finally, we create a 3-form Yang-Mills action and obtain the corresponding field equations.
