Semiclassical spectral instability of non-self-adjoint operators. II. (Instabilité spectrale semiclassique d’opérateurs non-autoadjoints. II.) (French) Zbl 1115.81032
Summary: In this work, we consider analytic (pseudo-)differential operators as well as random perturbations. We show for the perturbed operators that with probability almost 1, the eigenvalues inside a subdomain of the pseudospectrum are distributed according to a bidimensional Weyl law.
