In this paper, we prove the theorem, let M be an n-dimensional compact and without boundary manifold which is constant mean curvature immersed in an (n+p)-dimensional space of constant curvature a,then The square of the length of Riemann curvature tensor of M is defined by∑(Rijkl)2,The square of the length of Ricci curvature tensor of M is defined by∑(Rij)2,R is Scalar curvature of M... |
