Uniqueness results and enclosure properties for hypersurfaces with boundary in weighted cylinders

For a Riemannian manifold M, possibly with boundary, we consider the Riemannian product M×Rk with a smooth positive function that weights the Riemannian measures.

Description
Summary:For a Riemannian manifold M, possibly with boundary, we consider the Riemannian product M×Rk with a smooth positive function that weights the Riemannian measures. In this work we characterize parabolic hypersurfaces with non-empty boundary and contained within certain regions of M×Rk with suitable weights. Our results include half-space and Bernstein-type theorems in weighted cylinders. We also generalize to this setting some classical properties about the confinement of a compact minimal hypersurface to certain regions of Euclidean space according to the position of its boundary. Finally, we show interesting situations where the statements are applied, some of them in relation to the singularities of the mean curvature flow.
