主能量条件下紧致非退化层位的地表重力

Surface gravity of compact non-degenerate horizons under the dominant energy condition

Sebastian Gurriaran, Ettore Minguzzi

摘要:

证明了在优势能量条件下,任何非退化光滑紧致全测地视界都存在一个具有常非零表面引力的光滑切向量场。这一结果推广了以前的工作由伊森伯格和Moncrief,并由布斯塔曼特和Reiris的非真空的情况下,真空的情况下被给予了很大程度上独立的证明。此外,我们证明了任何这样的非时变性的非退化视界实际上是柯西视界的一个时间违反区域的一侧有界。

英文摘要:

We prove that under the dominant energy condition any non-degenerate smooth compact totally geodesic horizon admits a smooth tangent vector field of constant non-zero surface gravity. This result generalizes previous work by Isenberg and Moncrief, and by Bustamante and Reiris to the non-vacuum case, the vacuum case being given a largely independent proof. Moreover, we prove that any such achronal non-degenerate horizon is actually a Cauchy horizon bounded on one side by a chronology violating region.
