最小质量引力的常曲率解

Constant Curvature Solutions of Minimal Massive Gravity

Nejat Tevfik Yilmaz

摘要:

研究了最小质量引力场的常曲率解。在引入了一个关于物理度量和基准度量的条件以及在有效宇宙学常数存在的情况下将作用量截断为Einstein-Hilbert作用量的Stuckelberg标量之后,我们着重讨论了常曲率物理度量的约束方程的解。我们讨论了这些约束方程的两种不同的正式解决方案的方法,然后提出了一个明确的一类解决方案的Stuckelberg标量和基准度量引起的MMGR的常曲率解决方案。

英文摘要:

We study the constant curvature solutions of the minimal massive gravity (MMGR). After introducing a condition on the physical and the fiducial metrics as well as the Stuckelberg scalars which truncates the action to the Einstein-Hilbert one in the presence of an effective cosmological constant we focus on the solutions of the constraint equations written for the constant curvature physical metrics. We discuss two distinct formal solution methods for these constraint equations then present an explicit class of solutions for the Stuckelberg scalars and the fiducial metrics giving rise to constant curvature solutions of MMGR.
