渐近局部反de Sitter背景中的旋转圆柱

A rotating cylinder in an asymptotically locally anti-de Sitter background

J. B. Griffiths, N. O. Santos

摘要:

本文给出了一组精确解,它代表了一个在负宇宙学常数背景下的刚性旋转尘埃圆柱。无限长圆柱体的内部由哥德尔解描述。一个精确的解决方案的外部解决方案,发现这取决于旋转的内部和其半径。对于这些参数的值小于一定的限制,外部解决方案被证明是局部同构的Linet-Tian解决方案。对于大于另一个极限的值,它表明,外部解决方案延伸到一个区域,其中包含封闭的类时曲线。在距离源很远的地方,时空被证明是渐近局部anti-de Sitter空间。

英文摘要:

A family of exact solutions is presented which represents a rigidly rotating cylinder of dust in a background with a negative cosmological constant. The interior of the infinite cylinder is described by the Godel solution. An exact solution for the exterior solution is found which depends both on the rotation of the interior and on its radius. For values of these parameters less than a certain limit, the exterior solution is shown to be locally isomorphic to the Linet-Tian solution. For values larger than another limit, it is shown that the exterior solution extends into a region which contains closed timelike curves. At large distances from the source, the space-time is shown to be asymptotic locally to anti-de Sitter space.
