Title: The exterior Steklov problem: asymptotic results

础产蝉迟谤补肠迟:听In this talk, I will present recent asymptotic results for the exterior Steklov problem in the听complement of a compact Euclidean set. The Steklov problem is first rigorously posed for the听modified Helmholtz equation (p-Delta)u = 0 with a strictly positive parameter p. The asymptotic听behavior of the eigenvalues is then analyzed as p goes to 0. For unbounded domains, the asymptotic听formulas depend on the space dimension and exhibit non-analytic terms, i.e., the eigenvalues are听not analytic functions of the parameter p. Some open questions related to spectral, probabilistic听and numerical aspects of this spectral problem will be outlined.
