Unfolded Description of Kerr Black Hole
arXiv:0801.2213 · doi:10.1016/j.physletb.2008.05.067
Abstract
It is shown that Kerr black hole is a solution of simple unfolded differential equations that form a deformation of the zero-curvature description of empty space-time. Our construction uses the Killing symmetries of the Kerr solution. All known and some new algebraic properties of the Kerr-Schild solution result from the obtained black hole unfolded system in the coordinate-independent way. Kerr Schild type solutions of free equations in for massless fields of any spin, associated to the proposed black hole unfolded system, are found.
