Title: A new instability for higher dimensional black holes
Abstract: In contrast with the classical stability of stationary, asymptotically flat black holes in 3+1 dimensions, some families of higher dimensional black holes suffer from dynamical instabilities. I will discuss a subtle instability affecting a wide class of higher dimensional black holes which has not been previously observed in the literature. This new instability is, in a sense, more fundamental than the other known instability phenomena in higher dimensions and can be related to a precise geometric property of the class of spacetimes considered.
