Raed Hatamleh, Vladimir Alekseyevich Zolotarev · Zurnal matematiceskoj fiziki analiza geometrii · 2015
For an entirely non-selfadjoint operator with spectrum at zero, the imaginary component of which has an absolutely continuous spectrum (not necessarily dissipative and having lacunas in the spectrum), triangular and functional models are constructed.
