摘要：摘要：To study the Lawson-Osserman's counterexample to the Bernstein problem for minimal submanifolds of higher codimension, a new geometric concept, submanifolds in Euclidean space with constant Jordan angles(CJA), is introduced, which is a generalization of constant angle curves and surfaces. By exploring the second fundamental form of submanifolds with CJA,  we can characterize the Lawson-Osserman's cone  from the viewpoint of Jordan angles.
