Query: Optimizing the first eigenvalue of some quasilinear operators with
  respect to the boundary conditions   We consider a class of quasilinear operators on a bounded domain
$\Omega\subset \mathbb R^n$ and address the question of optimizing the first
eigenvalue with respect to the boundary conditions, which are of the
Robin-type. We describe the optimizing boundary conditions and establish upper
and lower bounds on the respective maximal and minimal eigenvalue.
