Das Cauchyproblem für die linearisierte Einsteingleichung und das Goursatproblem für Wellengleichungen

, 2018
In this thesis, we study two initial value problems arising in general relativity. The first is the Cauchy problem for the linearised Einstein equation on general globally hyperbolic spacetimes, with smooth and distributional initial data. We extend well-

On certain principal directions in lightlike hypersurfaces of an indefinite Sasakian manifold

Annals of the Alexandru Ioan Cuza University - Mathematics, 2022
In this paper, the geometry of some principal directions on a tangential lightlike hypersurface of an indefinite Sasakian manifold is investigated. In particular, we have proved, under some geometric conditions, that if the total space has constant ...
