Estimates for weighted eigenvalues of fourth-order elliptic operator with variable coefficients
We investigate the Dirichlet weighted eigenvalue problem for a fourth-order elliptic operator with variable coefficients in a bounded domain in Rⁿ. We establish a sharp inequality for its eigenvalues. It yields an estimate for the upper bound of the (k+1)-th eigenvalue in terms of the first k eigenv...
