关于整体静态分解唯一性的一个注记

A note on the uniqueness of global static decompositions

Miguel Sánchez, José M. M. Senovilla

摘要:

我们讨论静态Killing向量场是标准的,也就是说,导致一个全球性的时空正交分裂。我们证明了这样的正交分裂是唯一的,只要自然空间是紧的。这是通过证明许多著名的类空子流形必须包含在一个正交切片。还考虑了全局分裂的可能障碍。

英文摘要:

We discuss when static Killing vector fields are standard, that is, leading to a global orthogonal splitting of the spacetime. We prove that such an orthogonal splitting is unique whenever the natural space is compact. This is carried out by proving that many notable spacelike submanifolds must be contained in an orthogonal slice. Possible obstructions to the global splitting are also considered.
