An Inverse Eigenvalue Problem for Jacobi Matrices [PDF]
Mathematical Problems in Engineering, 2011 A kind of inverse eigenvalue problem is proposed which is the reconstruction of a Jacobi matrix by given four or five eigenvalues and corresponding eigenvectors. The solvability of the problem is discussed, and some sufficient conditions for existence of the solution of this problem are proposed.

Eigenvalue enclosures and exclosures for non-self-adjoint problems in hydrodynamics [PDF]
, 2010 In this paper we present computer-assisted proofs of a number of results in theoretical fluid dynamics and in quantum mechanics. An algorithm based on interval arithmetic yields provably correct eigenvalue enclosures and exclosures for non-self-adjoint ...

Three spectra inverse Sturm–Liouville problems with overlapping eigenvalues
Electronic Journal of Qualitative Theory of Differential Equations, 2017 In the paper we show that the Dirichlet spectra of three Sturm–Liouville differential operators defined on the intervals $[0,1]$, $[0,a]$ and $[a,1]$ for some $a\in (0,1)$ fixed, together with the knowledge of the normalizing constants corresponding to ...

On the Uniqueness of Inverse Eigenvalue Problems [PDF]
Geophysical Journal International, 1974 Summary The inverse eigenvalue problem consisting of the differential equation dZn) - (pl u@- yn- 1) + . . . + ( - 1)” p, u = AU together with suitable boundary conditions is examined. It is shown that n + 1 spectra associated with n + 1 distinct sets of boundary conditions are required in order to reconstruct the unknown coefficients pl, ...,p,.

Inverse eigenvalue problems for the mantle [PDF]
Geophysical Journal International, 1980 We represent the earth as a sphere with radius R and assume that the material is perfectly elastic and isotropic. Thus we ignore ellipticity, rotation, damping, lateral inhomogeneities and anisotropy.
