Abstract

We present some global results on Lorentzian geometry obtained by using global variational methods. In particular some results on the geodesic connectedness of Lorentzian manifolds and on the multiplicity of lightlike geodesics joining a point with a timelike curve are presented. Such I results allow to give a mathematical description of the gravitational lens effect.
