In this paper we complete some results of (J. Approx. Theory 69 (1992), 156-166) and give a geometrical approach to the multivariate Bernstein and Markov inequalities. The most interesting and slightly surprising result is a sharp Markov inequality for convex symmetric subsets of \(\mathbf{R}^{n}\)

Abstract
We study the Bernstein type problem for complete submanifolds in the space forms. In particular, we prove that any complete super stable minimal submanifolds in an (n + p)‐dimensional Euclidean space \documentclass{article}\usepackage{amssymb}\begin{document}\pagestyle{empty}$\mathbb {R}^{n+p},(n\le 5)$\end{document} with finite L^1^ norm of the second fundamental form must be affine n‐dimensional planes. We also prove that any complete noncompact weakly stable hypersurfaces in \documentclass{article}\usepackage{amssymb}\begin{document}\pagestyle{empty}$\mathbb {R}^{n+1},(n\le 5)$\end{document} with constant mean curvature and finite L^d^ (d = 1, 2, 3) norm of traceless second fundamental form must be hyperplanes.
