A lower bound for eigenvalues of a clamped plate problem
Qing-Ming Cheng, Guoxin Wei
In this paper, we study eigenvalues of a clamped plate problem. We obtain a lower bound for eigenvalues, which gives an important improvement of results due to Levine and Protter.
Universal bounds for eigenvalues of a buckling problem II
Qing-Ming Cheng, Hongcang Yang
In this paper, we investigate universal estimates for eigenvalues of a buckling problem. For a bounded domain in a Euclidean space, we give a positive contribution for obtaining a…
Estimates for lower order eigenvalues of a clamped plate problem
Qing-Ming Cheng, Guangyue Huang, Guoxin Wei
For a bounded domain in a complete Riemannian manifold , we study estimates for lower order eigenvalues of a clamped plate problem. We obtain universal inequalities for lo…
Embedded hypersurfaces with constant mean curvature in a unit sphere
Qing-Ming Cheng, Haizhong Li, Guoxin Wei
In this paper, we study -dimensional hypersurfaces with constant mean curvature in a unit sphere and construct many compact nontrivial embedded hype…
