Brans-Dicke几何中的大质量运动及其它

Massive motion in Brans-Dicke geometry and beyond

Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth

摘要:

可以被看作面积度规流形动力学的引力理论(Brans-Dicke理论是最近研究的一个例子),需要对它们的物理解释进行识别,识别出作为光和大质量物质轨道的独特曲线。作为对光传播的补充,我们研究了有效质量点粒子的运动。我们表明,相关的几何结构是一个特殊的Finsler范数所确定的面积度量,和大量的点粒子遵循Finsler测地线。

英文摘要:

Gravity theories that can be viewed as dynamics for area metric manifolds, for which Brans-Dicke theory presents a recently studied example, require for their physical interpretation the identification of the distinguished curves that serve as the trajectories of light and massive matter. Complementing previous results on the propagation of light, we study effective massive point particle motion. We show that the relevant geometrical structure is a special Finsler norm determined by the area metric, and that massive point particles follow Finsler geodesics.
