On the gravitational collapse in confined geometries | |||||

Abstract |
It was recently pointed out that anti-de Sitter(AdS) spacetime is unstable against gravitational collapse. The pertubation in AdS does not simply decay away and can be reflected by AdS boundary. Such waves nonlinearly interact with one another and the energy is transferred to higher modes, resulting in the black hole formation. It is also pointed out, however, that a particular initial data makes considerably long-lived bound-states and there would exist "stability islands". In this presentation, I would like to show our results and discuss open problems(role of confinement, initial data, and so on). |
