遥平行引力中某些非真空时空的能量含量

Energy Contents of Some Non-Vacuum Spacetimes in Teleparallel Gravity

M. Sharif, Sumaira Taj

摘要:

本文在广义相对论的遥平行等价框架下阐述了能量动量问题。为此目的,我们考虑能量动量处方来自的约束方程的积分形式中开发的远程平行等价的广义相对论的哈密顿公式。我们用这种方法来研究稳态轴对称爱因斯坦-麦克斯韦解和宇宙弦时空的能量-动量。这些时空的角动量,引力和物质的能量动量通量也进行了评估。结果表明,遥平行理论的结果与广义相对论的结果是比较相似的。

英文摘要:

This paper elaborates the problem of energy-momentum in the framework of teleparallel equivalent of General Relativity. For this purpose, we consider energy-momentum prescription derived from the integral form of the constraint equations developed in the Hamiltonian formulation of the teleparallel equivalent of General Relativity. We use this technique to investigate energy-momentum of stationary axisymmetric Einstein-Maxwell solutions and cosmic string spacetimes. The angular momentum, gravitational and matter energy-momentum fluxes of these spacetimes are also evaluated. It is concluded that the results of teleparallel theory are relatively analogous to the results of General Relativity.
