Inverse spectral theory for a class of non-compact Hankel operators (1803.06169v1)
Published 16 Mar 2018 in math.SP and math.CV
Abstract: We characterize all bounded Hankel operators $\Gamma $ such that $\Gamma*\Gamma$ has finite spectrum. We identify spectral data corresponding to such operators and construct inverse spectral theory including the characterization of these spectral data.
