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…

Local and global scalar curvature rigidity of Einstein manifolds
Mattias Dahl, Klaus Kroencke
An Einstein manifold is called scalar curvature rigid if there are no compactly supported volume-preserving deformation of the metric which increase the scalar curvature. We give v…
