Formation of quiescent big bang singularities
Hans Oude Groeniger, Oliver Petersen, Hans Ringström
Hawking's singularity theorem says that cosmological solutions arising from initial data with positive mean curvature have a past singularity. However, the nature of the singularit…
Conditional non-linear stability of Kerr-de Sitter spacetimes in the full subextremal range
Peter Hintz, Oliver Petersen, András Vasy
We show the stability of Kerr-de Sitter black holes, in the full subextremal range, as solutions of the vacuum Einstein equation with a positive cosmological constant under the ass…
The asymptotic expansion of the spacetime metric at the event horizon
Klaus Kroencke, Oliver Petersen
Hawking's local rigidity theorem, proven in the smooth setting by Alexakis-Ionescu-Klainerman, says that the event horizon of any stationary non-extremal black hole is a non-degene…
Stationarity and Fredholm Theory in Subextremal Kerr-de Sitter Spacetimes
Oliver Petersen, András Vasy
In a recent paper, we proved that solutions to linear wave equations in a subextremal Kerr-de Sitter spacetime have asymptotic expansions in quasinormal modes up to a decay order g…
