In this paper the authors investigate the three spectra problem of recovering the coefficients \(q_{1}\) and \(q_{2}\) of the Sturm-Liouville equation by the spectrum of some boundary problems on different intervals. Additionally, the authors introduce the notion positive Nevanlinna function of higher order.
