A note on geodesic connectedness of Gödel type spacetimes
R. Bartolo, A. M. Candela, J. L. Flores
In this note we reduce the problem of geodesic connectedness in a wide class of Gödel type spacetimes to the search of critical points of a functional naturally involved in the stu…
New Examples of Marginally Trapped Surfaces and Tubes in Warped Spacetimes
J. L. Flores, S. Haesen, M. Ortega
In the present paper we provide new examples of marginally trapped surfaces and tubes in FLRW spacetimes by using a basic relation between these objects and CMC surfaces in 3-manif…
Global hyperbolicity and Palais-Smale condition for action functionals in stationary spacetimes
Anna Maria Candela, Jose' Luis Flores, Miguel Sanchez
In order to apply variational methods to the action functional for geodesics of a stationary spacetime, some hypotheses, useful to obtain classical Palais-Smale condition, are comm…
Causality and Conjugate Points in General Plane Waves
J. L. Flores, M. Sánchez
Let be a pp--wave type spacetime endowed with the metric , where is any R…
