Electrogeodesics and Extremal Horizons in Kerr–Newman–(anti-)de Sitter
We review some properties of the Kerr–Newman–(anti-)de Sitter solution. We present admissible extremal configurations, but the main focus of this work is charged test particle motion in the equatorial plane and along the spacetime’s axis of rotation, with emphasis on static positions and effective potentials.
