Uniform stability of the inverse Sturm-Liouville problem on a star-shaped graph

E. E. Chitorkin, N. P. Bondarenko

In this paper, we study the inverse spectral problem for the Sturm-Liouville operators on a star-shaped graph, which consists in the recovery of the potentials from specral data or…

Uniform stability of the inverse Sturm-Liouville problem with polynomials in a boundary condition

N. P. Bondarenko, E. E. Chitorkin

This paper deals with the Sturm-Liouville problem with singular potential of the Sobolev space $W_{2}^{- 1}$ and polynomials of the spectral parameter in a boundary condition. We prov…
