论广义相对论角动量定义的正确性

On the validity of the definition of angular momentum in general relativity

Po-Ning Chen, Lan-Hsuan Huang, Mu-Tao Wang, Shing-Tung Yau

摘要:

我们检验了在没有宇称假设的情况下ADM角动量定义的有效性。给出了具有零ADM能量动量矢量和有限个非零角动量矢量的闵可夫斯基时空中渐近平坦超曲面的显式例子。我们还讨论了Beig-Murchadha-Regge-Teitelboim质心,并研究了史瓦西时空中类似的例子。

英文摘要:

We exam the validity of the definition of the ADM angular momentum without the parity assumption. Explicit examples of asymptotically flat hypersurfaces in the Minkowski spacetime with zero ADM energy-momentum vector and finite non-zero angular momentum vector are presented. We also discuss the Beig-Ó Murchadha-Regge-Teitelboim center of mass and study analogous examples in the Schwarzschild spacetime.
