Resumo:
In this work, as a suitable application of the well known generalized Maximum
Principle of Omori-Yau, we obtain rigidity results concerning to complete spacelike
hypersurfaces immersed in the half Hn+1 of the de Sitter spaceSn+11 , which models the
so-called steady state space. Moreover, by using an isometrically equivalent model for
Hn+1, we extend our results to a wider family of spacetimes. Finally, we also study the
uniqueness of entire vertical graphs in such ambient spacetimes.
