# Electromagnetic asymmetry, relegation of curvature singularities of charged black holes, and cosmological equations of state in view of the Born–Infeld theory

@article{Yang2022ElectromagneticAR, title={Electromagnetic asymmetry, relegation of curvature singularities of charged black holes, and cosmological equations of state in view of the Born–Infeld theory}, author={Yisong Yang}, journal={Classical and Quantum Gravity}, year={2022}, volume={39} }

It is shown that the Born–Infeld nonlinear electrodynamics with a polynomial type nonlinearity accommodates finite-energy electric point charges but rejects finite-energy magnetic point charges, or monopoles, thereby spelling out an electromagnetic asymmetry. Moreover, it is demonstrated, in a systematic way, that the curvature singularities of finite-energy charged black holes in the context of the Born–Infeld theory may effectively be relegated or in some cases removed under a critical mass…
