It has long been known that, in higher-dimensional general relativity, thereare black hole solutions with an arbitrarily large angular momentum for a fixedmass. We examine the geometry of the event horizon of such ultra-spinning blackholes and argue that these solutions become unstable at large enough rotation.Hence we find that higher-dimensional general relativity imposes an effective`Kerr-bound' on spinning black holes through a dynamical decay mechanism. Ourresults also give indications of the existence of new stationary black holeswith `rippled' horizons of spherical topology. We consider various scenariosfor the possible decay of ultra-spinning black holes, and finally discuss theimplications of our results for black holes in braneworld scenarios.Comment: 21 pages, typo's corrected, ref's adde
