等效于广义相对论的远程平行理论中的膜世界黑洞及其杀伤矢量、能量、动量和Angular-Momentum

Brane World black holes in Teleparallel Theory Equivalent to General Relativity and their Killing vectors, Energy, Momentum and Angular-Momentum

Gamal G. L. Nashed

摘要:

利用与坐标无关的能量动量张量计算了两个不同四元场的能量、动量和角动量。虽然这两个四分体场再现了相同的时空,但它们的能量是不同的。因此,一个正则化的表达式的引力能量动量张量的远程平行等价的广义相对论,(TEGR),是用来使两个四元组场的能量相等。引力能动量的定义被用来研究外部事件视界内的能量。计算了与这些时空相关的角动量分量。尽管我们使用的是静态时空,但我们得到的角动量分量不为零!因此,我们推导出与这些时空相关的杀伤矢量,使用的二阶张量的李导数的定义,在TEGR的框架,使图片更清晰。

英文摘要:

The energy-momentum tensor, which is coordinate independent, is used to calculate energy, momentum and angular-momentum of two different tetrad fields. Although, the two tetrad fields reproduce the same space-time their energies are different. Therefore, a regularized expression of the gravitational energy-momentum tensor of the teleparallel equivalent of general relativity, (TEGR), is used to make the energies of the two tetrad fields equal. The definition of the gravitational energy-momentum is used to investigate the energy within the external event horizon. The components of angular-momentum associated with these space-times are calculated. In spite that we use a static space-times, we get a non-zero component of angular-momentum! Therefore, we derive the killing vectors associated with these space-times using the definition of the Lie derivative of a second rank tensor in the framework of the TEGR to make the picture more clear.
