Abstract:
Let M n be a complete space-like hypersurface with constant normalized scalar curvature R in the de Sitter space S n + 1 1 and denote . We prove that if the norm square of the second fundamental form of M n satisfies , then either and M n is a totally umbilical hypersurface; or , and, up to rigid motion, M n is a hyperbolic cylinder .
