Estimates for Eigenvalues of the Elliptic Operator in Divergence Form on Riemannian Manifolds

Abstract EN

We investigate the Dirichlet weighted eigenvalue problem of the elliptic operator in divergence form on compact Riemannian manifolds (M,g,e-ϕdv).

We establish a Yang-type inequality of this problem.

We also get universal inequalities for eigenvalues of elliptic operators in divergence form on compact domains of complete submanifolds admitting special functions which include the Hadamard manifolds with Ricci curvature bounded below and any complete manifolds admitting eigenmaps to a sphere.
