The instability of anti-de Sitter space-time
Grégoire Martinon
In this review, we retrace the recent progress in the anti-de Sitter (AdS) instability problem. By instability we mean that for large classes of initial data, any perturbation of A…
Gravitational systems in asymptotically anti-de Sitter space-times
Grégoire Martinon
Being a key ingredient of the AdS/CFT correspondence, AdS space-time is suspected to be non-linearly unstable since 2011. Even with arbitrarily small initial data, a singularity al…
Gravitational geons in asymptotically anti-de Sitter spacetimes
Grégoire Martinon, Gyula Fodor, Philippe Grandclément +1
We report on numerical constructions of fully non-linear geons in asymptotically anti-de Sitter (AdS) spacetimes in four dimensions. Our approach is based on 3+1 formalism and spec…
Rotating proto-neutron stars: spin evolution, maximum mass and I-Love-Q relations
Grégoire Martinon, Andrea Maselli, Leonardo Gualtieri +1
Shortly after its birth in a gravitational collapse, a proto-neutron star enters in a phase of quasi-stationary evolution characterized by large gradients of the thermodynamical va…
