报告摘要：

Recently, various models have been proposed for regular black holes. We provide a systematic analysis for the classification and construction of effective polymerized spherically symmetric hamiltonians and their underlying extended mimetic gravity Lagrangians with higher derivatives. This presents a framework for the construction of regular black holes with a limiting curvature mechanism. This framework allows for the embedding of various regular black hole models through the reconstruction of the corresponding mimetic Lagrangian, enabling the study of their (inhomogeneous) dust collapse. In this talk, an overview of this classification and reconstruction will be given, including examples of bouncing solutions and solutions with a regular center, such as Bardeen and Hayward black holes.
