Energy and angular momentum of general 4-dimensional stationary axi-symmetric spacetime in teleparallel geometry

Gamal Gergess Lamee Nashed

摘要:

本文导出了引力场和电磁场耦合的四元引力理论的一般轴对称精确解。该溶液由四个参数$M$(质量)、$Q$(电荷)、$a$(旋转)和$L$(NUT)表征。然后,在Weitzenb $\ddot{o}$ ck几何的框架下,利用Møller给出的能量-动量复合体计算总外能.我们表明,包含在一个球的能量是由其内部以及外部共享。我们还计算了空间动量的分量,以评估角动量分布。我们证明了角动量的唯一非零分量是在Z方向上。

英文摘要:

We derive an exact general axi-symmetric solution of the coupled gravitational and electromagnetic fields in the tetrad theory of gravitation. The solution is characterized by four parameters $M$ (mass), $Q$ (charge), $a$ (rotation) and $L$ (NUT). We then, calculate the total exterior energy using the energy-momentum complex given by Møller in the framework of Weitzenb$\ddot{o}$ck geometry. We show that the energy contained in a sphere is shared by its interior as well as exterior. We also calculate the components of the spatial momentum to evaluate the angular momentum distribution. We show that the only non-vanishing components of the angular momentum is in the Z direction.
