Inverse problems for ZS-operators and their isomorphisms

Spectral Theory 2025-12-11 v1

Abstract

Consider two inverse problems for ZS-operators problems on the unit interval. It means that there are two corresponding mappings F,fF, f from a Hilbert space of potentials HH into their spectral data. They are called isomorphic if FF is a composition of ff and some isomorphism UU of HH onto itself. We consider isomorphic inverse problems for ZS-operators on the unit interval under basic boundary conditions and on the circle. The proof is based on the non-linear analysis and properties of the 4-spectra mapping constructed in our paper.
