A note on the extendability of compact hypersurfaces to smooth Cauchy hypersurfaces
Antonio N. Bernal, Miguel Sánchez
This paper has been withdrawn because the new one gr-qc/0512095 includes all its results (as well as those in gr-qc/0511016) in a clearer way.
Smooth globally hyperbolic splittings and temporal functions
Antonio N. Bernal, Miguel Sánchez
Geroch's theorem about the splitting of globally hyperbolic spacetimes is a central result in global Lorentzian Geometry. Nevertheless, this result was obtained at a topological le…
Geodesics in stationary spacetimes. Application to Kerr spacetime
Jose Luis Flores, Miguel Sanchez
The Levi-Civita connection and geodesic equations for a stationary spacetime are studied in depth. General formulae which generalize those for warped products are obtained. These r…
Geodesic connectedness of multiwarped spacetimes
Jose L. Flores, Miguel Sanchez
A new technique for the study of geodesic connectedness in a class of Lorentzian manifolds is introduced. It is based on arguments of Brouwer's topological degree for the solution…
