In this work we characterize parabolic hypersurfaces with non-empty boundary and contained within certain regions of M×ℝ^k 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.Mean curvature flowSingularitiesStability & uniquenessMinimal & CMC surfaces
