The first law of black hole mechanics in conformal Einstein-Power-Yang-Mills theory
Xiaokai He, Xiaoning Wu, Naqing Xie
In the framework of the Iyer-Wald formalism, the first law of black hole mechanics is examined within the context of conformal Einstein-power-Yang-Mills (CEPYM) theory. By comparin…
Symmetric black-to-white hole solutions with a cosmological constant
