Asymptotic analysis of the eigenvalues of an elliptic problem in an anisotropic thin multidomain

Abstract

We study, via an asymptotic analysis, an elliptic eigenvalue problem in a 1D–1D multidomain and in a 1D–2D multidomain filled with anisotropic material. The corresponding isotropic cases were considered in a previous work by Gaudiello and Sili.
