Anti-de Sitter空间中的振动壳

Oscillating Shells in Anti-de Sitter Space

Javier Mas, Alexandre Serantes

摘要:

研究了d维Anti-de Sitter时空中理想流体球对称薄壳的动力学。在整体坐标下,除了坍缩解外,还发现了壳在两个半径之间来回弹跳的振荡解。这些振荡的解决方案存在的参数空间被扫描在任意数量的维度。正如预期的那样,AdS 3似乎被挑出来。

英文摘要:

We study the dynamics of a spherically symmetric thin shell of perfect fluid embedded in d-dimensional Anti-de Sitter space-time. In global coordinates, besides collapsing solutions, oscillating solutions are found where the shell bounces back and forth between two radii. The parameter space where these oscillating solutions exist is scanned in arbitrary number of dimensions. As expected AdS3 appears to be singled out.
