The Pseudospectrum of the Zakharov-Shabat System

Published 31 Oct 2013 in nlin.SI and math.AP | (1310.8365v2)

Abstract: We study the pseudospectrum of the non-selfadjoint Zakharov-Shabat system in the semiclassical regime. The pseudospectrum may be defined as the union of the spectra of perturbations of the Zakharov-Shabat system, thus it is relevant to the numerical computation of true eigenvalues.
