This work describes new perturbative solutions to the classical, four-dimensional Kerr-Newman dilaton black hole field equations. Our solutions do not require the black hole to be slowly rotating. The unperturbed solution is taken to be the ordinary Kerr solution and the perturbation parameter is effectively the square of the charge-to-mass ratio [Formula presented] of the Kerr-Newman black hole. The solutions show the expected conjugation (mirror) symmetry, which maps the small coupling sector to the strong coupling sector [Formula presented].

Abstract

This work describes new perturbative solutions to the classical, four-dimensional Kerr-Newman dilaton black hole field equations. Our solutions do not require the black hole to be slowly rotating. The unperturbed solution is taken to be the ordinary Kerr solution and the perturbation parameter is effectively the square of the charge-to-mass ratio [Formula presented] of the Kerr-Newman black hole. The solutions show the expected conjugation (mirror) symmetry, which maps the small coupling sector to the strong coupling sector [Formula presented]. We also calculate the gyromagnetic ratio of the black hole. © 1997 The American Physical Society.
