圆柱对称爱因斯坦方程的静态解

Static solutions of Einstein's equations with cylindrical symmetry

Cynthia S. Trendafilova, Stephen A. Fulling

摘要:

在类比的史瓦西解的标准偏差,我们发现所有静态的,圆柱对称的解决方案的爱因斯坦场方程真空。这些不仅包括众所周知的锥解,这是局部平坦的,但其他的度量系数是权力的径向坐标和时空弯曲。这些解出现在文献中,但以不同的形式,对应于径向坐标的不同定义。由于所有的真空解在轴上都是奇异的,我们试图将它们与具有非零能量密度和压力的“内部”解相匹配。除了众所周知的“宇宙弦”的解决方案加入到锥,我们发现一些数值解加入到其他外部解决方案。

英文摘要:

In analogy with the standard derivation of the Schwarzschild solution, we find all static, cylindrically symmetric solutions of the Einstein field equations for vacuum. These include not only the well known cone solution, which is locally flat, but others in which the metric coefficients are powers of the radial coordinate and the space-time is curved. These solutions appear in the literature, but in different forms, corresponding to different definitions of the radial coordinate. Because all the vacuum solutions are singular on the axis, we attempt to match them to "interior" solutions with nonvanishing energy density and pressure. In addition to the well known "cosmic string" solution joining on to the cone, we find some numerical solutions that join on to the other exterior solutions.
