论文摘要
我们解决了一个问题，即定期黑洞或其他施瓦茨柴尔德解决方案的替代方案是否可能来自量子重力的动作原理。着眼于此类溶液的渐近扩展并检查相应的场方程，我们证明了它们在固定作用原则中的实现将需要微调或在重力有效作用中强大的红外非局部性。这表明大距离区域与许多经典黑洞的替代品之间存在不相容性。
We tackle the question of whether regular black holes or other alternatives to the Schwarzschild solution can arise from an action principle in quantum gravity. Focusing on an asymptotic expansion of such solutions and inspecting the corresponding field equations, we demonstrate that their realization within a principle of stationary action would require either fine-tuning, or strong infrared non-localities in the gravitational effective action. This points to an incompatibility between large-distance locality and many of the proposed alternatives to classical black holes.
