Query: The Pseudospectral Properties of non-self-adjoint Schr\"odinger
  Operators in the semi-classical limit   We describe the general qualitative behaviour of the resolvent norm for a
very wide class of non-self-adjoint Schroedinger operators in the
semi-classical regime, as the spectral parameter varies over the complex plane.
