We study low type submanifolds in pseudo-Euclidean space which is especially of 2-type pseudo-umbilical. We also determine full null 2-type surfaces with parallel mean curvature vector in 4-dimensional Minkowski space-time.
Keywords: pseudo-Riemannian submanifolds, pseudo-Euclidean spaces, finite-type, pseudo-umbilical submanifolds
