On G-convergence of positive Self-adjoint operators

Abstract

We apply G-convergence theory to study the asymptotic of the eigenvalue problems of positive definite bounded self-adjoint $h$-dependent operators as $h\to \infty$. Two operators are considered; a second order elliptic operator and a general linear operator. Using the definition of G-convergence of elliptic operator, we review convergence results of the elliptic eigenvalue problem as $h\to \infty$. Also employing the general definition of G-convergence of positive definite self-adjoint operator together with $\Gamma$-convergence of the associated quadratic form, we characterize the G-limit as $h\to \infty$ of the general operator with some classes of perturbations. As a consequence, we also prove the convergence of the corresponding spectrum.
