Stability of Spacelike Hypersurfaces in Foliated Spacetimes
A. Barros, A. Brasil, A. Caminha
Abstract
We show that a given x:Mn Mn+1=I×ϕFn closed spacelike hypersurface with constant mean curvature H and warping function ϕ satisfying ϕ''≥ \Hϕ'',0\ is either minimal or a spacelike slice \to\× F for some to∈ I$.
