On overspinning of black holes in higher dimensions

Abstract

It turns out that repulsive effect due to rotation of a rotating black hole dominates over attraction due to mass for large rr in dimensions >5>5. This gives rise to a remarkable result that black hole in these higher dimensions in contrast to lower dimensional ones cannot be overspun even under linear test particle accretion. Further if a black hole in dimension >4>4 has one of its rotation parameters zero, it has only one horizon and hence it can never be overspun. Thus rotating black holes in six and higher dimensions, and those with one rotation parameter switched off, would always obey the weak cosmic censorship conjecture (WCCC).
