匹配定态时空

Matching stationary spacetimes

Filipe C. Mena, Jose Natario

摘要:

利用拟Maxwell形式,我们得到了两个定常时空沿定常类时超曲面匹配的充要条件,用引力场和引力磁场以及空间流形上的二维匹配面表示.我们证明了具有球对称、平面对称、双曲对称和柱对称的静止完美流体时空的匹配问题的存在性和唯一性结果。最后,我们找到了一个明确的内部的圆柱模拟的NUT时空。

英文摘要:

Using the quasi-Maxwell formalism, we derive the necessary and sufficient conditions for the matching of two stationary spacetimes along a stationary timelike hypersurface, expressed in terms of the gravitational and gravitomagnetic fields and the 2-dimensional matching surface on the space manifold. We prove existence and uniqueness results to the matching problem for stationary perfect fluid spacetimes with spherical, planar, hyperbolic and cylindrical symmetry. Finally, we find an explicit interior for the cylindrical analogue of the NUT spacetime.
