论文摘要
作为球体对称性污染重力的球形对称真空溶液产生的常规黑洞溶液具有渐近的内部结构，通过非旋转BTZ度量的四维概括很好地描述了渐近的内部结构。根据这张图片，没有奇异性，而是，插入的观察者在朝着未来的无效无穷大时经历了持续的曲率歧管。这是BTZ事件视野的特征。还研究了黑洞的外部结构，并证明它对应于Schwarzschild溶液，前提是黑洞质量不太小。这样，常规的黑洞状态可以看作是一个时空，它连接两个恒定曲率渐近空间，即外部区域中的平坦Minkowski时空，而本地广告中恒定的负曲率表征了BTZ样渐近造的内部。
The regular black hole solution arising as a spherically symmetric vacuum solution of Born-Infeld gravity possesses an asymptotic interior structure which is very well described by a four dimensional generalization of the non-rotating BTZ metric. According to this picture no singularity exists, and instead, infalling observers experience a constant curvature manifold as they travel towards future null infinity. This is characterized by the BTZ event horizon. The exterior structure of the black hole is also studied, and it is shown that it corresponds to the Schwarzschild solution provided the black hole mass is not too small. In this way, the regular black hole state can be seen as a spacetime which connects two constant curvature asymptotic spaces, namely, the flat Minkowski spacetime in the outside region, and the locally AdS constant negative curvature one characterizing the BTZ-like asymptotic interior.
