大质量引力中的含时几何
Time Dependent Geometry in Massive Gravity
摘要:
在本文中,我们将分析在一个有质量的引力理论中的一个依赖于时间的几何。这将通过在这样一个巨大的引力理论中分析Vaidya时空来完成。由于引力坍缩是一个依赖于时间的系统,我们将使用大质量引力下的Vaidya时空来分析它。Vainshtein和dRGT机制被用来获得一个鬼自由的质量引力,并构造这样的时间相关的解决方案。奇点的形成,它们的性质和强度将被详细研究。我们还将通过计算这样一个系统的重要物理量,并分析这些量的物理行为来研究这样一个几何的物理方面。
英文摘要:
In this paper, we will analyze a time dependent geometry in a massive theory of gravity. This will be done by analyzing Vaidya space-time in such a massive theory of gravity. As gravitational collapse is a time dependent system, we will analyze it using the Vaidya space-time in massive gravity. The Vainshtein and dRGT mechanisms are used to obtain a ghost free massive gravity, and construct such time dependent solutions. Singularities formed, their nature and strength will be studied in detail. We will also study the thermodynamical aspects of such a geometry by calculating the important thermodynamical quantities for such a system, and analyzing the thermodynamical behavior of such quantities.
