Some inequalities for eigenvalues of an elliptic differential operator

Abstract

‎In the present paper, we investigate the eigenvalues of an elliptic differential operator on compact Riemannian manifolds with boundary and derive a general inequality for these eigenvalues. Applying this inequality, we give universal estimates for eigenvalues on compact domains of complete submanifolds in an Euclidean space, and of complete manifolds admitting special functions. Finally, we find universal bounds on the $(k+1)$-th eigenvalue on such objects in terms of the first $k$ eigenvalues independent of the domains.
