Stability of determinacy and inverse spectral problems for Jacobi operators
Rafael del Rio, Luis O. Silva
This work studies the interplay between Green functions, the index of determinacy of spectral measures and interior finite rank perturbations of Jacobi operators. The index of dete…

Inverse problems for Jacobi operators IV: Interior mass-spring perturbations of semi-infinite systems
Rafael del Rio, Mikhail Kudryavtsev, Luis O. Silva
This work gives results on the interplay of the spectra of two Jacobi operators corresponding to an infinite mass-spring system and a modification of it obtained by changing one ma…
