Birkhoff定理与物质

Birkhoff Theorem and Matter

Rituparno Goswami, George F. R. Ellis

摘要:

球对称真空时空的Birkhoff定理是广义相对论中研究局域系统的一个关键定理。然而,现实的局域系统只是近似球对称的,并且只是近似真空的。在以前的论文中,我们证明了定理仍然近似正确的近似球对称真空时空。在本文中,我们证明了相反的情况下:定理仍然近似正确的球对称,近似真空时空。

英文摘要:

Birkhoff's theorem for spherically symmetric vacuum spacetimes is a key theorem in studying local systems in general relativity theory. However realistic local systems are only approximately spherically symmetric and only approximately vacuum. In a previous paper, we showed the theorem remains approximately true in an approximately spherically symmetric vacuum space time. In this paper we prove the converse case: the theorem remains approximately true in a spherically symmetric, approximately vacuum space time.
