论文摘要
对球体对称静态的常规黑洞和球形对称的非单数宇宙学时空的简短综述。考虑了几种常规黑洞的型号，包括新孔。首先，研究了一大批具有内部DE Sitter核心的常规黑洞，并研究了凯奇·地平线的相关问题。然后，将黑色的弹跳空间时间（因此缺乏Cauchy Horizon以及相关的不稳定性）被讨论为具有内在的Sitter Core的常规黑洞的有效替代方案。还讨论了Friedman-Lemaitre-Robertson-Walker空间时期承认定期反弹解决方案。在有关运动方程中存在或不存在奇异性的一般分析中，强调了由于Osgood引起的定理的作用。
A short review on spherically symmetric static regular black holes and spherically symmetric non singular cosmological space-time is presented. Several models of regular black holes, including new ones, are considered. First, a large class of regular black holes having an inner de Sitter core with the related issue of Cauchy horizon is investigated. Then, black bounce space-times, where the Cauchy horizon and therefore the related instabilities are absent, are discussed as valid alternatives of regular black holes with inner de Sitter core. Friedman-Lemaitre-Robertson-Walker space-times admitting regular bounce solutions are also discussed. In the general analysis concerning the presence or absence of singularities in the equations of motion, the role of a theorem due to Osgood is stressed.
