Free boundary hypersurfaces with nonpositive Yamabe invariant in mean convex manifolds
A. Barros, C. Tiarlos Cruz
We obtain some estimates on the area of the boundary and on the volume of a certain free boundary hypersurface with nonpositive Yamabe invariant in a Riemannian -manifold wi…

Stability of Spacelike Hypersurfaces in Foliated Spacetimes
A. Barros, A. Brasil, A. Caminha
We show that a given closed spacelike hypersurface with constant mean curvature and warping function satisfying ϕ''\geq \ma\{Hϕ'',0\…
