静态和非静态宇宙弦时空中的能量动量分布

Energy-momentum Distribution in Static and Non-static Cosmic String Space-times

Amir M. Abbassi, Saeed Mirshekari, Amir H. Abbassi

摘要:

利用能量-动量处方理论阐述了广义相对论中的能量-动量问题。在这方面,我们计算M \oller,朗道-利夫希茨,Papapetrou,爱因斯坦,伯格曼,托尔曼和温伯格的能量动量复合物在静态和非静态宇宙弦时空。我们得到的结果之间的强吻合。这些巧合可以被认为是Virbhadra观点的延伸,不同的能量-动量处方可以提供一些基础来定义一个唯一的量。此外,我们的结果不同意Lessner关于M \oller的处方的信念,并支持Virbhadra关于爱因斯坦处方的力量的结论。

英文摘要:

We elaborate the problem of energy-momentum in general relativity by energy-momentum prescriptions theory. In this regard, we calculate M\oller,Landau-Lifshitz, Papapetrou, Einstein, Bergman, Tolman, and Weinberg's energy-momentum complexes in static and nonstatic cosmic string space-times. We obtain strong coincidences between the results. These coincidences can be considered as an extension of Virbhadra's viewpoint that different energy-momentum prescriptions may provide some basis to define a unique quantity. In addition, our results disagree with Lessner's belief about M\oller's prescription and support the Virbhadra's conclusion about the power of Einstein's prescription.
