时空对称性和平行引力对称解快速指南

A quick guide to spacetime symmetry and symmetric solutions in teleparallel gravity

Christian Pfeifer

摘要:

时空对称性的概念对于描述行星、恒星、黑洞或整个宇宙等引力物理系统是必不可少的,因为它们至少在很好的近似下分别具有球面对称性、轴对称性或空间均匀性和各向同性对称性。这篇文章给出了一个快速的概述,在时空对称性的已知事实,在telepallel引力。本文给出了Weitzenbck规范中最一般的球对称、轴对称或空间均匀各向同性的四元组,并对$f(T,B,ϕ,X)$ -引力中反对称场方程的对称解作了简要的讨论。

英文摘要:

The notion of spacetime symmetry is essential to describe gravitating physical systems like planets, stars, black holes, or the universe as a whole, since they possess, at least to good approximation, spherical, axial, or spatially homogeneous and isotropic symmetry, respectively. This article gives a quick overview over the known facts on spacetime symmetries in teleparallel gravity. The most general spherical, axial, or spatially homogeneous and isotropic tetrads in Weitzenbck gauge are presented and a brief discussion about symmetric solutions of the anti-symmetric field equations in $f(T,B,ϕ,X)$-gravity is given.
