广义相对论的准麦克斯韦方程组在微扰论中的应用

The Quasi-Maxwellian Equations of General Relativity: Applications to the Perturbation Theory

M. Novello, E. Bittencourt, J. M. Salim

摘要:

本文综述了Jordan、Ehlers和Kundt提出的准麦克斯韦(QM)形式的广义相对论方程。我们的主要兴趣是将其应用于Friedman-Lemaintre-Robertson-Walker框架中标准宇宙学的微扰分析。QM方案的主要成就是它使用了完全与规范无关的量。我们将看到,在QM-方案中,我们直接处理可观测量。这揭示了它的优势,由Lifshitz等人介绍的老方法,处理在标准爱因斯坦框架中的微扰。为了完整性,我们比较QM计划的规范独立的方法的Barthel,一个程序组成的特定选择的扰动变量作为一个组合的规范依赖量。

英文摘要:

A comprehensive review of the equations of general relativity in the quasi-Maxwellian (QM) formalism introduced by Jordan, Ehlers and Kundt is made. Our main interest concerns its applications to the analysis of the perturbation of standard cosmology in the Friedman-Lemaître-Robertson-Walker framework. The major achievement of the QM scheme is its use of completely gauge independent quantities. We shall see that in the QM-scheme we deal directly with observable quantities. This reveals its advantage over the old method introduced by Lifshitz et al that deals with perturbation in the standard Einstein framework. For completeness, we compare the QM-scheme to the gauge-independent method of Bardeen, a procedure consisting on particular choices of the perturbed variables as a combination of gauge dependent quantities.
