Abstract: | In this paper we generalize the explicit formulas for constant mean curvature (CMC) immersion of hypersurfaces of Euclidean
spaces, spheres and hyperbolic spaces given in Perdomo (Asian J Math 14(1):73–108, 2010; Rev Colomb Mat 45(1):81–96, 2011) to provide explicit examples of several families of immersions with constant mean curvature and non constant principal curvatures,
in semi-Riemannian manifolds with constant sectional curvature. In particular, we prove that every
h ? -1,-\frac2?{n-1}n)h\in-1,-\frac{2\sqrt{n-1}}{n}) can be realized as the constant curvature of a complete immersion of
S1n-1×\mathbbRS_1^{n-1}\times \mathbb{R} in the (n + 1)-dimensional de Sitter space S1n+1\hbox{\bf S}_1^{n+1}. We provide 3 types of immersions with CMC in the Minkowski space, 5 types of immersion with CMC in the de Sitter space and
5 types of immersion with CMC in the anti de Sitter space. At the end of the paper we analyze the families of examples that
can be extended to closed hypersurfaces. |
