高维真空Einstein方程的代数特殊轴对称解

Algebraically special axisymmetric solutions of the higher-dimensional vacuum Einstein equation

Mahdi Godazgar, Harvey S. Reall

摘要:

一个d维时空是“轴对称的”,如果它拥有一个SO(d-2)等距群,其轨道是(d-3)-球。本文研究了高维真空Einstein方程(含宇宙学常数)的代数特殊轴对称解。给出了静态轴对称解属于不同代数类的充要条件。然后一般(可能依赖于时间)轴对称的解决方案进行了讨论。得到了代数型II、D、III和N的所有轴对称解。

英文摘要:

A d-dimensional spacetime is "axisymmetric" if it possesses an SO(d-2) isometry group whose orbits are (d-3)-spheres. In this paper, algebraically special, axisymmetric solutions of the higher dimensional vacuum Einstein equation (with cosmological constant) are investigated. Necessary and sufficient conditions for static axisymmetric solutions to belong to different algebraic classes are presented. Then general (possibly time-dependent) axisymmetric solutions are discussed. All axisymmetric solutions of algebraic types II, D, III and N are obtained.
