AdS--dS Stationary Rotating Black Hole Exact Solution within Einstein--Nonlinear Electrodynamics

Abstract: In this report the exact rotating charged black hole solution to the Einstein--nonlinear electrodynamics theory with a cosmological constant is presented. This black hole is equipped with mass, rotation parameter, electric and magnetic charges, cosmological constant $\Lambda$, and three parameters due to the nonlinear electrodynamics: $\beta$ is associated to the potential vectors $A_\mu$ and ${}^{\star}P_\mu$, and two constants, $F_0$ and $G_0$, due to the presence of the invariants $F$ and $G$ in the Lagrangian $L(F(\,x^{\mu}),G(\,x^{\mu}))$. This solution is of Petrov type D, characterized by the Weyl tensor eigenvalue $\Psi_2$, the traceless Ricci tensor eigenvalue $S=2\Phi_{(11)}$, and the scalar curvature $R$; it allows for event horizons, exhibits a ring singularity and fulfils the energy conditions. Its Maxwell limit is the de Sitter-Anti--de Sitter--Kerr--Newman black hole solution.
