space-like submanifold%second fundamental form%scalar curvature
In this paper,we study the complete space-like submanifold Mn with constant scalar curvature R≤ c in the de Sitter space Snp+P(c) and obtain a pinching condition for Mn to be totally umbilical ones.The result generalizes that in [5,Main Theorem] to higher codimension and give a complement for n= 2 there.
