引力反问题的一族解:围绕度规建立理论

A family of solutions to the inverse problem in gravitation: building a theory around a metric

Arthur G. Suvorov

摘要:

给出了一种构造特殊的非极小耦合标量-张量理论的方法,使得给定的度规是该理论的精确真空解。与引力动力学研究中的标准方法不同,在标准方法中,人们从一个作用开始,然后求解运动方程,这种方法允许围绕一些预先指定的几何形状建立一个明确的理论。从一个参数化的黑洞时空与通用的,非克尔头发,它显示了如何一个总体家庭的理论可以被设计成完全符合度量。

英文摘要:

A method is presented to construct a particular, non-minimally coupled scalar-tensor theory such that a given metric is an exact vacuum solution in that theory. In contrast to the standard approach in studies of gravitational dynamics, where one begins with an action and then solves the equations of motion, this approach allows for an explicit theory to be built around some pre-specified geometry. Starting from a parameterized black hole spacetime with generic, non-Kerr hairs, it is shown how an overarching family of theories can be designed to fit the metric exactly.
