Eigenvectors from eigenvalues: the case of one-dimensional Schrödinger operators (Q2218250)

Following the study [\textit{P. B. Denton} et al., ``Eigenvectors from eigenvalues: a survey of a basic identity in linear algebra'', Preprint, \url{arXiv:1908.03795}], the authors extend the eigenvector-eigenvalue identity (this name was given by the authors of [loc. cit.]) for \(n\times n\) matrices to one dimensional self-adjoint Dirichlet Schrödinger operators on compact intervals.
