论文摘要
我们研究了DGP Brane中带有带电的Taub-Nut时空解决方案。我们表明，Einstein-Maxwell重力的Reissner-Nordstrom-taub-nut-De固定器解解决了相应的运动方程，其中宇宙常数与DGP模型中的交叉量表有关。遵循Teitelboim在讨论Sitter Spacetime的热力学和Wu等人的建议的方法之后。对于与螺母参数相关的保守电荷，我们获得了广义的Smarr质量公式和时空热力学的第一定律。
We study a charged Taub-NUT spacetime solution in the DGP brane. We show that the Reissner-Nordstrom-Taub-NUT-de Sitter solution of Einstein-Maxwell gravity solves the corresponding equations of motion, where the cosmological constant is related to the cross-over scale in the DGP model. Following the approach by Teitelboim in discussing the thermodynamics of de Sitter spacetime and the proposal by Wu et al. for a conserved charge associated to the NUT parameter, we obtained the generalized Smarr mass formula and the first law of thermodynamics of the spacetime.
