Title
A new instability for higher dimensional black holes
Abstract
In contrast with the classical stability of stationary, asymptotically flat black holes in four dimensions, some families of higher dimensional black holes suffer from dynamical instabilities. By presenting a mathematical theorem on five-dimensional black rings recently proven in my doctoral thesis, I will argue for the existence of a new instability affecting not only black rings, but a wide class of higher dimensional black holes. This new instability can be directly related to a geometric property of higher dimensional black holes and should be seen as the manifestation of a more general dispersive phenomenon independent of the global, algebraic nature of the spacetime considered.
