Title: Localized nonlinear gravitational waves - "geons" - in asymptotically
anti de Sitter space-times.
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 space-times
with respect to black hole formation.
