Rigidity results for complete spacelike submanifolds in plane fronted waves Palomo, Francisco J. Romero Sarabia, Alfonso Extremal submanifold Weakly trapped submanifold Plane fronted wave 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. 2022-10-03T07:13:33Z 2022-10-03T07:13:33Z 2022-09-08 journal article Palomo, F.J., Pelegrín, J.A.S. & Romero, A.
