Sturm-Liouville differential operators with deviating argument. (English) Zbl 1410.34230
Summary: Non-selfadjoint second-order differential operators with a constant delay are studied. We establish properties of the spectral characteristics and investigate the inverse problem of recovering operators from their spectra. For this inverse problem the uniqueness theorem is proved.
