摘要
本文对五维转动压扁黑洞进行新的研究.首先通过直接求解真空中的Einstein场方程,得到转动不带电的压扁黑洞解比较简单的新形式,然后利用抵消项方法研究其热力学性质.本文给出的转动不带电的压扁黑洞解的新形式及其相关的热力学表达式与先前他人给出的结果相比,显得非常简洁、优美,为下一步研究五维转动带电的压扁黑洞做好了热身准备.
We have revisited the five-dimensional rotating squashed black hole. By solving directly the vacuum Einstein field equation, we have obtained a new but rather simple form for the rotating uncharged black hole with squashed horizons. This new metric expression for the rotating squashed black hole is very convenient for us to investigate its thermodynamics by means of the counterterm method. Compared with the previous results given by the other author, not only is our new metric form of the neutral rotating squashed black hole much more simple, but also its associated thermodynamic expressions are very concise and elegant. Our present work can serve as a warmup preparation for studying the rotating charged squashed black hole in the near future.
