In the present work, we study complete spacelike hypersurfaces with constant scalar curvature and have sectional curvatures K(phi;) ?1 in de Sitter space S16(1) and find a result on the type number of such a hypersurface. © 2010 Academic Journals.eninfo:eu-repo/semantics/closedAccessHypersurfacesPrimary 53c40Scalar curvatureSecondary 53c15Type numberArticle2-s2.0-779547542082984N/A2935
