Today, at the Institute seminar, professor of Firat University of Turkey Etibar Panahov gave a talk on “Some inverse problems of spectral issues of differential operators”.
Second order differential operators with singular points in special form (Bessel, and Coulomb type), the inverse problems for canonical Dirac operator and diffusion equation with respect to two or one spectrum, partially given potential were investigated. The inverse problems for nodal data (Points and lengths) were considered. Asymptotic formulas for nodal data were shown. Uniqueness theorems were proved.
