具有物质场的李代数体Yang Mills

Lie Algebroid Yang Mills with Matter Fields

Christoph Mayer, Thomas Strobl

摘要:

李代数体Yang-Mills理论是Yang-Mills规范理论的推广,用李代数体E代替结构李代数。本文放宽了作用泛函的规范不变性对E的纤维度规的条件。耦合到标量场可能需要李代数胚的非线性表示。在所有的情况下,规范不变性被认为是导致一个条件的协变常数对相应的纤维度规的问题,相对于一个适当的李代数体连接。演示文稿保持部分明确,以便也可以访问较少的数学导向的观众。

英文摘要:

Lie algebroid Yang-Mills theories are a generalization of Yang-Mills gauge theories, replacing the structural Lie algebra by a Lie algebroid E. In this note we relax the conditions on the fiber metric of E for gauge invariance of the action functional. Coupling to scalar fields requires possibly nonlinear representations of Lie algebroids. In all cases, gauge invariance is seen to lead to a condition of covariant constancy on the respective fiber metric in question with respect to an appropriate Lie algebroid connection. The presentation is kept in part explicit so as to be accessible also to a less mathematically oriented audience.
