The teleparallel gravity, in the weak field approximation, is considered. In the Schwarzschild space–time the gravitational Stefan–Boltzmann law is calculated. Using the first law of thermodynamics, the Hawking entropy and temperature of the black hole are calculated. Thermofield dynamics formalism is used to define the temperature-dependent theory. In addition the gravitational Casimir effect and Stefan–Boltzmann law at zero and finite temperature are calculated in Schwarzschild space–time.

重新审视霍金熵

考虑弱场近似中的远平行重力。在 Schwarzschild 时空中，计算了引力 Stefan-Boltzmann 定律。利用热力学第一定律，计算了黑洞的霍金熵和温度。热场动力学形式用于定义温度相关理论。此外，在 Schwarzschild 时空中计算了零和有限温度下的引力卡西米尔效应和 Stefan-Boltzmann 定律。
