Abstract By means of heinz omogeneizzati the two-scale convergence method, we investigate the asymptotic behavior of eigenvalues and eigenfunctions of Stekloff eigenvalue problems in perforated domains.We prove a concise and precise homogenization result including convergence of gradients of eigenfunctions which improves the understanding of the asymptotic behavior of eigenfunctions.It is also justified that claus porto bath soap the natural local problem is not an eigenvalue problem.
