Résumé
The Steklov eigenvalue problem is an eigenvalue problem for an operator which is defined in the boundary of a domain. Since the operator is nonlocal, the eigenvalues depend on both the geometries of the interior and the boundary of the domain. In this talk, we consider the Steklov-Dirichlet eigenvalue problem in eccentric annuli and related problems. We obtain a lower bound of the first Steklov-Dirichlet eigenvalues of the eccentric annuli by analyzing the first eigenvalues if the distance between the boundary components are sufficiently close. This is based on joint work with Jiho Hong and Mikyoung Lim.
