A gap for eigenvalues of a clamped plate problem
Daguang Chen, Qing-Ming Cheng, Guoxin Wei
This paper studies eigenvalues of the clamped plate problem on a bounded domain in an -dimensional Euclidean space. We give an estimate for the gap between $\sqrt {Γ_{k+1}-Γ_{1}…

Estimates for the first eigenvalue of Jacobi operator on hypersurfaces with constant mean curvature in spheres
Daguang Chen, Qing-Ming Cheng
In this paper, we study the first eigenvalue of Jacobi operator on an -dimensional non-totally umbilical compact hypersurface with constant mean curvature in the unit sphere…

Estimates for eigenvalues of a system of of elliptic equations and of the biharmonic operator
Daguang Chen, Qing-Ming Cheng, Qiaoling Wang +1
Let $\om $ be a bounded domain in an -dimensional Euclidean space . We study eigenvalues of an eigenvalue problem of a system of elliptic equations: $$ \{\aligned &Δ{\…
