Reductions of Thermodynamic Phase Space for Rotating Regular Black Holes

The black hole singularity problem was proposed by Hawking and Penrose, and regular black holes serve as an important class of models to address this issue. However, the study of regular black hole thermodynamics has long faced a fundamental difficulty: an inconsistency between the Hawking temperature derived from thermodynamics and the geometrically defined Hawking temperature. To address this issue, we systematically investigated the thermodynamics of rotating regular black holes based on the method of thermodynamic phase space reduction. Our research shows that this approach naturally yields a self-consistent and complete thermodynamic description for rotating regular black holes, thereby establishing a universal thermodynamic framework for this type of black hole and laying the foundation for further research on complex thermodynamic phenomena.
