摘要

在Brans-Dicke-Maxwell理论中考虑了Weyl曲率与电磁场的非极小耦合。引力场方程在黎曼时空中由拉格朗日乘子的方法以外部微分形式表达，其中时空扭转被约束为零。在pp波时空中研究了引力非极小耦合的意义和分支。

A nonminimally coupled, conformally extended Einstein-Maxwell theory of pp-waves

A non-minimal coupling of Weyl curvatures to electromagnetic fields is considered in Brans-Dicke-Maxwell theory. The gravitational field equations are formulated in a Riemannian spacetime where the spacetime torsion is constrained to zero by the method of Lagrange multipliers in the language of exterior differential forms. The significance and ramifications of non-minimal couplings to gravity are examined in a pp-wave spacetime.
