• Mean curvature of spacelike submanifolds in a Brinkmann spacetime 

      Cánovas, Verónica L.; Romero, Alfonso; Palomo-Ruiz, Francisco Jose (2021)
      Several geometric properties of complete spacelike submanifolds, with codimension at least two, in a Brinkmann spacetime are shown from natural assumptions involving the mean curvature vector field $\mcv$ of the spacelike ...
    • Rigidity results for complete spacelike submanifolds in plane fronted waves 

      Palomo-Ruiz, Francisco Jose; Pelegrín, José A. S.; Romero, Alfonso (Springer, 2022-09-08)
      New rigidity results for complete non-compact spacelike submanifolds of arbitrary codimension in plane fronted waves are obtained. Under appropriate assumptions, we prove that a complete spacelike submanifold in these ...
