论文摘要
黑洞的存在是一般相对论（GR）的关键预测之一，因此是对重力理论的基本一致性测试。在GR中的球形对称性的情况下，明显的视野的存在，其规律性仅与两种不同类别的物理黑洞一致。在这里，我们得出了约束，即任何自洽修改的重力理论都必须满足才能与它们的存在兼容。我们使用Starobinsky模型分析了它们的特性，并说明了特征。在该模型的扰动溶液中，这两种GR溶液都可以视为零阶项。我们还展示了如何在没有明确定义的GR极限的情况下构建非扰动解决方案。
The existence of black holes is one of the key predictions of general relativity (GR) and therefore a basic consistency test for modified theories of gravity. In the case of spherical symmetry in GR the existence of an apparent horizon and its regularity is consistent with only two distinct classes of physical black holes. Here we derive constraints that any self-consistent modified theory of gravity must satisfy to be compatible with their existence. We analyze their properties and illustrate characteristic features using the Starobinsky model. Both of the GR solutions can be regarded as zeroth-order terms in perturbative solutions of this model. We also show how to construct nonperturbative solutions without a well-defined GR limit.
