报告摘要  Abstract

We consider the Steklov spectral problem for the Laplacian with  
singular perturbation on the boundary. One case is when we have a  
small part of the boundary with Dirichlet boundary condition and the  
second case is a rapidly changing boundary conditions (Steklov and  
Dirichlet). We construct limit problems and prove the convergence of  
eigenvalues and eigenfunctions.
