RT Journal Article T1 Rigidity results for complete spacelike submanifolds in plane fronted waves A1 Palomo-Ruiz, Francisco José A1 Pelegrín, José A. S. A1 Romero, Alfonso K1 Subvariedades AB 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 spacetimes is contained in a characteristic lightlike hypersurface. Moreover, for a complete codimension two extremal submanifold in a plane fronted wave we show sufficient conditions to guarantee that it is a (totally geodesic) wavefront.
