[0906.2367] Uniqueness of Extremal Kerr and Kerr-Newman Black Holes

Authors: Aaron J. Amsel, Gary T. Horowitz, Donald Marolf, Matthew M. Roberts

Abstract: We prove that the only four dimensional, stationary, rotating, asymptotically flat vacuum black hole with a single degenerate horizon is given by the extremal Kerr solution. We also prove a similar uniqueness theorem for the extremal Kerr-Newman solution. This closes a longstanding gap in the black hole uniqueness theorems.
