Abstract
Let $M^n$ be an $n(n\geq 3)$-dimensional complete connected and oriented spacelike hypersurface in a de Sitter space or an anti-de Sitter space, $S$ and $K$ be the squared norm of the second fundamental form and Gauss-Kronecker curvature of $M^n$. If $S$ or $K$ is constant, nonzero and $M^n$ has two distinct principal curvatures one of which is simple, we obtain some characterizations of the Riemannian products: $S^{n-1}(a) \times H^{1}(\sqrt{a^2-1})$, or $H^{n-1}(a) \times H^1(\sqrt{1-a^2})$.
