Asymptotic behavior of the spectrum of an elliptic problem in a domain with aperiodically distributed concentrated masses
Gregory Aleksandrovich Chechkin, Tatiana P. Chechkina · Comptes Rendus Mécanique · 2017
In this paper, we consider a spectral problem with singular perturbation of density located near the boundary of the domain, depending on a small parameter. We prove the compactness theorem and study the behavior of eigenelements to the given problem, as the small parameter tends to zero.
