Abstract

We prove that an $m$-dimensional minimal variety in a Riemannianmanifold cannot touch the boundary at a point where the sum of thesmallest $m$ principal curvatures is greater than 0. We prove astronger maximum principle in case the variety is a hypersurface.We also prove analogous results for varieties with bounded mean curvature.
