Eigenvalue approximations by mixed methods
— We study an abstract eigenvalue problem related to a saddle-point formulation, and then we discretize it, obtaining error bounds for eigenvalues and eigenfunctions. We apply our results to the solution of four th order problems by mixed finite element methods. INTRODUCTION We are interested in the following eigenvalue problem: Find X e R and (u, >\f) e V x W such that v)+b(v9 v|/) = 0, VweF, ...
متن کاملExtrapolation of Mixed Finite Element Approximations for the Maxwell Eigenvalue Problem
In this paper, a general method to derive asymptotic error expansion formulas for the mixed finite element approximations of the Maxwell eigenvalue problem is established. Abstract lemmas for the error of the eigenvalue approximations are obtained. Based on the asymptotic error expansion formulas, the Richardson extrapolation method is employed to improve the accuracy of the approximations for ...
متن کاملPostprocessing and Higher Order Convergence of Mixed Finite Element Approximations of Biharmonic Eigenvalue Problems
A new procedure for accelerating the convergence of mixed finite element approximations of the eigenpairs and of the biharmonic operator is proposed. It is based on a postprocessing technique that involves an additional solution of a source problem on an augmented finite element space. This space could be obtained either by substantially refining the grid, the two-grid method, or by using the s...
متن کاملOn estimators for eigenvalue/eigenvector approximations
We consider a large class of residuum based a posteriori eigenvalue/eigenvector estimates and present an abstract framework for proving their asymptotic exactness. Equivalence of the estimator and the error is also established. To demonstrate the strength of our abstract approach we present a detailed study of hierarchical error estimators for Laplace eigenvalue problems in planar polygonal reg...

— The paper is devote d to the finit e element analysis of second order e Hipt ie eigenvalue problems in the case when the approximate domains Oh are not subdomains of the original domain fl a U. The considérations are restricted to piecewise linear approximations and in the case of eigenfunctions to simple eigenvalues. The optimum rates of convergence for hoth the approximate eigenvalues and t...
