The spacelike-characteristic Cauchy problem of general relativity in low regularity

Stefan Czimek, Olivier Graf

In this paper we study the spacelike-characteristic Cauchy problem for the Einstein vacuum equations. We prove that given initial data on a maximal compact spacelike hypersurface $…

The canonical foliation on null hypersurfaces in low regularity

Stefan Czimek, Olivier Graf

Let $H$ denote the future outgoing null hypersurface emanating from a spacelike 2-sphere $S$ in a vacuum spacetime $(M, g)$ . In this paper we study the…

The localised bounded $L^{2}$ -curvature theorem

Stefan Czimek

In this paper, we prove a localised version of the bounded $L^{2}$ -curvature theorem of Klainerman-Rodnianski-Szeftel. More precisely, we consider initial data for the Einstein vacuu…
