Duality invariance for black holes in N=2 gauged Supergravity

Abstract

Electric-magnetic duality invariance of extended Supergravity theories has been a very powerful tool in the study of extremal black holes. A minimal extension is presented to black holes in N = 2, U(1)-gauged Supergravity theory, where duality covariance is preserved. These solutions are particularly interesting as they exist also in asymptotically AdS4 space. Their peculiar features are discussed, in particular the supersymmetry preserved by the scalar flow and the appearance of a charged quantization condition between the black hole and gravitini charges.
