We discuss symmetry properties of black holes in general relativity-known as black hole rigidity-of which basic assertion is that the event horizon of an asymptotically flat, stationary black hole with certain matter fields must be a Killing horizon and is rephrased (combined together with staticity results) that such a black hole must be either static, or axisymmetric. A precise formulation of the rigidity theorem for black holes with non-degenerate event horizon in arbitrary spacetime dimensions has been recently made by Hollands, Wald and the present author. [Hollands, S., Ishibashi, A. and Wald, R. M., Commun. Math. Phys. 271 (2007), 699.] In our formulation, no assumptions concerning the topology of cross-sections of event horizon (other than the compactness) are made. Therefore, different from Hawking's original proof given in 4-dimensions, our proof applies also to non-spherical black holes, which are known to occur in higher dimensions but not in 4-dimensions.
