DESCRIPTION:Title: The exterior Steklov problem: asymptotic results\n\nAbst
 ract: In this talk\, I will present recent asymptotic results for the exte
 rior Steklov problem in the complement of a compact Euclidean set. The Ste
 klov problem is first rigorously posed for the modified Helmholtz equation
  (p-Delta)u = 0 with a strictly positive parameter p. The asymptotic behav
 ior of the eigenvalues is then analyzed as p goes to 0. For unbounded doma
 ins\, the asymptotic formulas depend on the space dimension and exhibit no
 n-analytic terms\, i.e.\, the eigenvalues are not analytic functions of th
 e parameter p. Some open questions related to spectral\, probabilistic and
  numerical aspects of this spectral problem will be outlined.\n\nWhere: CR
