来源于p-形式的高维Robinson-Trautman时空:静态和辐射黑洞

Higher dimensional Robinson-Trautman spacetimes sourced by p-forms: static and radiating black holes

Marcello Ortaggio, Jiri Podolsky, Martin Zofka

摘要:

我们总结了在$n\ge 4$维中存在排列的$p$形式的麦克斯韦场和任意宇宙学常数的Robinson-Trautman时空的结果。在奇维空间中,这些解可以简化为带有电场和磁场(具有爱因斯坦空间视界)的静态黑洞,而在偶维空间中,它们也可以描述黑洞通过接收(或发射)电磁辐射获得(或失去)质量。在所有可能的情况下,时空的外尔型也作了简要的讨论。

英文摘要:

We summarize results about Robinson-Trautman spacetimes in the presence of an aligned $p$-form Maxwell field and an arbitrary cosmological constant in $n\ge 4$ dimensions. While in odd dimensions the solutions reduce to static black holes dressed with an electric and a magnetic field (with an Einstein space horizon), in even dimensions $2p=n$ they may also describe black holes gaining (or losing) mass by receiving (or emitting) electromagnetic radiation. The Weyl type of the spacetimes is also briefly discussed in all the possible cases.
