## Abstract We consider the problem to reconstruct the mass distribution of a string where the mass is concentrated in a finite number of points, or, equivalently, the problem to reconstruct a simply connected mass spring system with unknown masses and stiffness parameters if the following data are
We consider the problem of determining a radially symmetric potential in the three-dimensional SchrΓΆdinger equation from eigenvalues associated with two different angular-momentum quantum numbers. This leads to a singular eigenvalue problem for which there are no known general uniqueness results for
Simple, new, direct methods are derived for constructing real, symmetric, bordered-diagonal and tridiagonaf matrices from their eigenvalues and the eigenvalues of any one of their principal submatrices. A direct method is also presented for constructing, from its eigenvalues, a real tridiagonaf mat
