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…
