Abstract. We investigate hypersurfaces in Euclidean space . Two main results are obtained, one concerns the Gauss-Kronecker curvature of a graph defined by a radially symmetric function on , and the other gives a sufficient and necessary condition for a hypersurfaces to be hypersurfaces of revolution.
