Abstract

In this paper, we present a type D, non-vanishing cosmological constant, vacuum solution of the Einstein's field equations, extension of an axially symmetric, asymptotically flat vacuum metric with a curvature singularity. The space-time admits closed time-like curves (CTCs) that appear after a certain instant of time from an initial spacelike hypersurface, indicating it represents a time-machine space-time. We wish to discuss the physical properties and show that this solution can be interpreted as gravitational waves of Coulomb-type propagate on anti-de Sitter space backgrounds. Our treatment focuses on the analysis of the equation of geodesic deviation.
具有曲率奇点的轴对称宇宙学常数场方程的真空解,封闭类时曲线和测地线偏差
在本文中,我们给出了一个D型,不消失的宇宙常数,爱因斯坦场方程的真空解,一个轴对称的,具有曲率奇点的渐近平坦真空度规的扩展。时空允许封闭类时曲线(ctc)出现在初始类空超表面的某一时刻之后,表明它代表了一个时间机器时空。我们希望讨论物理性质,并表明该解可以解释为库仑型引力波在反德西特空间背景上传播。我们的处理重点是对测地线偏差方程的分析。
