Hawking's local rigidity theorem without analyticity
S. Alexakis, A. D. Ionescu, S. Klainerman
We prove the existence of a Hawking Killing vector-field in a full neighborhood of a local, regular, bifurcate, non-expanding horizon embedded in a smooth vacuum Einstein space-tim…

Uniqueness results for ill posed characteristic problems in curved space-times
Alexandru D. Ionescu, Sergiu Klainerman
We prove two uniqueness theorems for solutions of linear and nonlinear wave equations; the first theorem is in the Minkowski space while the second is in the domain of outer commun…

On the uniqueness of smooth, stationary black holes in vacuum
Alexandru D. Ionescu, Sergiu Klainerman
We prove a conditional "no hair" theorem for smooth manifolds: if is the domain of outer communication of a smooth, regular, stationary Einstein vacuum, and if a technical cond…
