Hypersurfaces of Constant Higher Order Mean Curvature in $M\times \mathbb{R}$

R. F. de Lima, F. Manfio, J. P. dos Santos

We consider hypersurfaces of products $M\times \mathbb{R}$ with constant $r$-th mean curvature $H_r\ge 0$ (to be called $H_r$-hypersurfaces), where $M$ is an arbitrary Riemannian $n$…
