一般球对称时空中的能量动量公式

Energy-momentum Prescriptions in General Spherically Symmetric Space-times

Saeed Mirshekari, Amir M. Abbassi

摘要:

研究了一般球对称时空中的爱因斯坦、朗道-利夫希茨、帕帕佩特鲁、温伯格和默勒能量-动量公式。它表明,对于两个特殊的,但并不罕见的类一般球对称时空的几个能量-动量处方在史瓦西笛卡尔坐标导致一些重合的能量分布。对于一类特殊的球对称度规,Møller和Einstein能量-动量公式对能量分布给出了相同的结果当且仅当能量分布对径向坐标有特定的依赖性.

英文摘要:

Einstein, Landau-Lifshitz, Papapetrou, Weinberg, and Møller energy-momentum prescriptions in general spherically symmetric space-times are investigated. It is shown that for two special but not unusual classes of general spherically symmetric space-times several energy-momentum prescriptions in Schwarzschild Cartesian coordinates lead to some coincidences in energy distribution. It is also obtained that for a special class of spherically symmetric metrics Møller and Einstein energy-momentum prescriptions give the same result for energy distribution if and only if it has a specific dependence on radial coordinate.
