Abstract: |
In this paper, we study Chen's inequalities for submanifolds of a Riemannian manifold of quasi-constant curvature. By using algebraic techniques, we establish Chen's general inequalities, Chen-Ricci inequalities and inequalities between the warping function and the squared mean curvature, which generalize several rusults of Özgür and Chen's. |
Key words: Chen's inequalities Chen-Ricci inequalities warped product quasi-constant curvature |
