Abstract
In this paper,we study the complete space-like submanifolds Mn with constant scalar curvature in a locally symmetric pesudo-Riemannian manifold Nn+pp.We discuss the pinching problem on the square of the length of the second fundamental form S mainly by making use of the generalized maximal principle of Yau and self-adjoint operator,and obtain a rigidity theorem for Mn being totally geodesic.关键词
