Uniform full stability of recovering convolutional perturbation of the Sturm-Liouville operator from the spectrum
Sergey Buterin
The perturbation of the Sturm-Liouville operator on a finite interval with Dirichlet boundary conditions by a convolution operator is considered. Local stability and global unique…
