(反)de Sitter时空中的引力电磁学

Gravitoelectromagnetism in (Anti) de Sitter Spacetime

Clovis Jacinto de Matos

摘要:

在爱因斯坦场方程中存在非零宇宙学项可以解释为在不破坏广义协方差的情况下,优选参考系的物理可能性。这种可能性被用于在德西特背景下线性化爱因斯坦场方程的过程中,以及在引力电磁学的框架下制定所得的方程。有人提出,这组方程只适用于物理真空,而不适用于重子(正常)物质。

英文摘要:

The presence of a non-zero cosmological term in Einstein field equations can be interpreted as the physical possibility for preferred reference frames without breaking of general covariance. This possibility is used in the process of linearizing Einstein field equations in a de Sitter background, and in formulating the resulting equations in the framework of gravitoelectromagnetism. It is proposed that this set of equations only applies to the physical vacuum and not to baryonic (normal) matter.
