DESCRIPTION:Steklov eigenvalues of submanifolds with prescribed boundary in
  Euclidean space.\n\nLet S be a fixed closed (n-1)-dimensional submanifold
  of Euclidean space R^{n+1}. I will discuss upper and lower bounds for the
  Steklov eigenvalues sigma_k(M)\, where M is any compact manifold with bou
 ndary S. An upper bound will be given\, in term of the volume of M. This i
 s based on methods from metric geometry. In the particular situation where
  S is the unit sphere S^{n-1} (lying in a coordinate hyperplane) and M is 
 an hypersurface of revolution\, I will prove that sigma_k(M)geq sigma_k(B^
 n) with equality if and only M is the n-dimensional ball B^n. This based o
 n joint work with Bruno Colbois (Neuchâtel) and Katie Gittins (MPIM Bonn).
