关于Kerr-NUT时空的正则化:I

On the Regularization of Kerr-NUT spacetime: I

G. G. L. Nashed

摘要:

在广义相对论远程平行等价(TEGR)理论框架下,利用与坐标无关的引力能-动量和黎曼联络1-形式${\widetildeΓ_α}^β$两种方法计算了Kerr-NUT时空的总能量和动量.已经表明,这两种方法给出了相同的不可接受的结果,即,不同的价值。因此,一个局部的洛伦兹变换,发挥了正则化工具的作用,它减去惯性效应,而不扭曲真正的引力贡献,已被建议。这种变换使所得到的时空保持为TEGR运动方程的解。

英文摘要:

Within the framework of teleparallel equivalent of general relativity (TEGR) theory, calculation of the total energy and momentum of Kerr-NUT spacetimes have been employed using two methods of the gravitational energy-momentum, which is coordinate independent, and the Riemannian connection 1-form, ${\widetildeΓ_α}^β$. It has been shown that the two methods give the same an unacceptable result, i.e., divergent value. Therefore, a local Lorentz transformation that plays a role of a regularizing tool, which subtracts the inertial effects without distorting the true gravitational contribution, has been suggested. This transformation keeps the resulting spacetime to be a solution of the equations of motion of TEGR.
