Schwarzschild-de Sitter时空的整体Hawking温度:拓扑方法

Global Hawking Temperature of Schwarzschild-de Sitter Spacetime: a Topological Approach

Charles W. Robson, Leone Di Mauro Villari, Fabio Biancalana

摘要:

我们介绍了一个计算,基于纯粹的拓扑推理,全球平衡霍金温度的史瓦西-德西特时空,史瓦西黑洞视界共存的德西特宇宙视界。我们的方法是基于对整个系统的欧拉特征线的仔细计算,表明这个量完全决定了系统的几何特征。该方法具有普适性,适用于广义相对论中任何具有多视界的结构。

英文摘要:

We introduce a calculation, based on purely topological reasoning, of the global equilibrium Hawking temperature of the Schwarzschild-de Sitter spacetime, where a Schwarzschild black hole horizon coexists with a de Sitter cosmological horizon. Our method is based on the careful calculation of the Euler characteristic of the total system, showing that this quantity completely determines the thermodynamical features of the system. The method is universal and can be applied to any structure possessing multiple horizons in general relativity.
