Title: Localized nonlinear gravitational waves - geons - in asymptotically anti de Sitter spacetimes.
Abstract:
I present some numerically constructed remarkable solutions of the Einstein equations which are time periodic - hence non-radiating - and are spatially localized. These solutions are also of relevance in view of the conjectured instability of asymptotically AdS spacetimes with respect to black hole formation.
