Uniqueness of spacelike hypersurfaces with constant higher order mean curvature in generalized Robertson-Walker spacetimes
Luis J. Alias, A. Gervasio Colares
In this paper we study the problem of uniqueness for spacelike hypersurfaces with constant higher order mean curvature in generalized Robertson-Walker (GRW) spacetimes. In particul…

Spacelike hypersurfaces with constant mean curvature in the steady state space
Alma L. Albujer, Luis J. Alias
We consider complete spacelike hypersurfaces with constant mean curvature in the open region of de Sitter space known as the steady state space. We prove that if the hypersurface i…

Calabi-Bernstein results for maximal surfaces in Lorentzian product spaces
Alma L. Albujer, Luis J. Alias
In this paper we establish new Calabi-Bernstein results for maximal surfaces immersed into a Lorentzian product space of the form , where is a connecte…
