  • Geodesically Complete Lorentzian Metrics on Some Homogeneous 3 Manifolds 
    Bromberg, S.; Medina, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    In this work it is shown that a necessary condition for the completeness of the geodesics of left invariant pseudo-Riemannian metrics on Lie groups is also sufficient in the case of 3-dimensional unimodular Lie groups, and ...
