Iso-bispectral potentials for Sturm-Liouville-type operators with small delay
Nebojša Djurić, Sergey Buterin
In recent years, there appeared a considerable interest in the inverse spectral theory for functional-differential operators with constant delay. In particular, it is well known th…

On non-uniqueness of recovering Sturm-Liouville operators with delay and the Neumann boundary condition at zero
Nebojša Djurić, Sergey Buterin
As is known, for each fixed the spectra of two operators generated by and the boundary conditions uniquely d…
