论文摘要
我们计算并阐明了对安慰剂空间中Reissner-Nordström黑洞的壳壳欧几里德作用的解释。我们表明，壳的作用是为任意质量的黑洞和宇宙学的熵的总和。这种统一的表达有助于清除对De Sitter中极端和超低黑洞的欧几里得作用的混乱，因为它们可以理解为一般表达的特殊情况。然后，我们使用此结果来估计通过采用约束激体的形式主义，在空旷的de Sitter背景中对黑洞的成对产生的概率。最后，我们建议带电的DE Sitter黑洞的衰减受熵函数的梯度流动的控制，因此，光，超级，快速电荷发射的状态应描述极端带电的Nariai黑洞对单数几何形状的潜在衰减。
We compute and clarify the interpretation of the on-shell Euclidean action for Reissner-Nordström black holes in de Sitter space. We show the on-shell action is minus the sum of the black hole and cosmological horizon entropy for arbitrary mass and charge in any number of dimensions. This unifying expression helps to clear up a confusion about the Euclidean actions of extremal and ultracold black holes in de Sitter, as they can be understood as special cases of the general expression. We then use this result to estimate the probability for the pair creation of black holes with arbitrary mass and charge in an empty de Sitter background, by employing the formalism of constrained instantons. Finally, we suggest that the decay of charged de Sitter black holes is governed by the gradient flow of the entropy function and that, as a consequence, the regime of light, superradiant, rapid charge emission should describe the potential decay of extreme charged Nariai black holes to singular geometries.
