Query: Convergence of eigenvalues for a highly non-self-adjoint differential
  operator   In this paper we study a family of operators dependent on a small parameter
$\epsilon > 0$, which arise in a problem in fluid mechanics. We show that the
spectra of these operators converge to N as $\epsilon \to 0$, even though, for
fixed $\epsilon > 0$, the eigenvalue asymptotics are quadratic.
