Inverse problems for finite Jacobi matrices and Krein--Stieltjes strings
arXiv:2505.06143 · doi:10.1515/jiip-2020-0112
Abstract
We consider dynamic inverse problems for a dynamical system associated with a finite Jacobi matrix and for a system describing propagation of waves in a finite Krein-Stieltjes string. We offer three methods of recovering unknown parameters: entries of a Jacobi matrix in the first problem and point masses and distances between them in the second, from dynamic Dirichlet-to-Neumann operators. We also answer a question on a characterization of dynamic inverse data for these two problems.
