On Eigenvalue and Eigenvector Estimates for Nonnegative Definite Operators
In this article we further develop a perturbation approach to the Rayleigh– Ritz approximations from our earlier work. We both sharpen the estimates and extend the applicability of the theory to nonnegative definite operators . The perturbation argument enables us to solve two problems in one go: We determine which part of the spectrum of the operator is being approximated by the Ritz values an...
متن کاملEigenvalue Estimates for Random Schrödinger Operators
where γ ≥ 0 for d ≥ 3, γ > 0 for d = 2 and γ ≥ 1/2 for d = 1. The estimate (1.1) is called the classical Lieb-Thirring inequality. One needs to remark, that although for any V ∈ L the eigenvalue sum ∑ j |λj| converges for both V and −V , it follows from our results that converse need not be true. The sum ∑ j |λj| can converge even for potentials that are not functions of the class L . In the pr...
متن کاملError Representation Formula for Eigenvalue Approximations for Positive Definite Operators
The main contribution of this paper is an error representation formula for eigenvalue approximations for positive definite operators defined as quadratic forms. The formula gives an operator theoretic framework for treating discrete eigenvalue approximation/estimation problems for unbounded positive definite operators independent of the multiplicity. Furthermore, by the use of the error represe...
متن کاملBenchmark Results for Testing Adaptive Finite Element Eigenvalue Procedures Ii (cluster Robust Eigenvector and Eigenvalue Estimates)
As a model benchmark problem for this study we consider a highly singular transmission type eigenvalue problem which we study in detail both analytically as well as numerically. In order to justify our claim of cluster robust and highly accurate approximation of a selected groups of eigenvalues and associated eigenfunctions, we give a new analysis of a class of direct residual eigenspace/vector...
متن کاملEigenvalue Estimates for Schrödinger Operators on Metric Trees
We consider Schrödinger operators on regular metric trees and prove LiebThirring and Cwikel-Lieb-Rozenblum inequalities for their negative eigenvalues. The validity of these inequalities depends on the volume growth of the tree. We show that the bounds are valid in the endpoint case and reflect the correct order in the weak or strong coupling limit.
