Abstract

We study complete spacelike hypersurfaces immersed in an open region of the de Sitter space S1n+1\mathbb{S}^{n+1}_{1} which is known as the steady state space Hn+1\mathcal{H}^{n+1}. In this setting, under suitable constraints on the behavior of the higher order mean curvatures of these hypersurfaces, we prove that they must be spacelike hyperplanes of Hn+1\mathcal{H}^{n+1}. Nonexistence results concerning these spacelike hypersurfaces are also given. Our approach is based on a suitable extension of the Omori-Yau's generalized maximum principle due to Al\'{\i}as, Impera and Rigoli in [5].
