Abstract By means of 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 justifie... https://www.marcelovicente.com/product-category/gentle-shampoo/
