摘要
Our purpose is to study the geometry of linear Weingarten spacelike hypersurfaces immersed in the de Sitter space . In this setting, by using as main analytical tool a suitable maximum principle for complete noncompact Riemannian manifolds, we establish new characterizations of the hyperbolic cylinders of . In the compact case, we obtain a rigidity result concerning to a such hypersurface according to the length of its second fundamental form.
