Abstract :We investigate totally umbilical $r$-null submanifolds of generalized Robertson-Walker space forms. Using generalized Newton transformations, we obtain new geometric configurations for the mean curvature functions which generalize many well-known results on null geometry.
Keywords : Generalized Robertson Walker space form, totally umbilical null submanifold
