To date, a mathematically consistent construction of effective rotating black hole models in the context of Loop Quantum Gravity (LQG) is still lacking. In this work, we start with the assumption that rotating LQG black hole metrics can be effectively obtained using Newman–Janis Algorithm. Then, based on a few extra fair assumptions on the seed metric functions, we make a conjecture on what a rotating LQG black hole would generically look like. Our general arguments and conclusions can be supported by some known specific examples in the literature.

关于旋转环量子黑洞可能的时空结构

迄今为止，仍然缺乏在环量子引力（LQG）背景下有效的旋转黑洞模型的数学上一致的构建。在这项工作中，我们首先假设使用 Newman-Janis 算法可以有效地获得旋转 LQG 黑洞度量。然后，基于对种子度量函数的一些额外公平的假设，我们推测旋转的 LQG 黑洞一般会是什么样子。我们的一般论点和结论可以得到文献中一些已知的具体例子的支持。
