Inverse eigenvalue problem via finite-difference three-diagonal Schrödinger operator

چکیده
In present article the self-contained derivation of eigenvalue inverse problem results is given by using a discrete approximation with three-diagonal SturmLiouville operator on a finite interval. It is demonstrated that inverse problem procedure is nothing else than well known Gram-Schmidt orthonormalization in Euclidean space for special vectors numbered by space coordinate index. All the results of usual inverse problem with continuous coordinate are reobtained by employing a limiting procedure, including reproducing an equivalent equation in partial derivatives for the solutions of the inverse problem equations – the Goursat problem which guarantees the solvability of the inverse problem equations.

Inverse eigenvalue problem for discrete three - diagonal Sturm - Liouville operator and the continuum limit
In present article the self-contained derivation of eigenvalue inverse problem results is given by using a discrete approximation of the Schrödinger operator on a bounded interval as a finite three-diagonal symmetric Jacobi matrix. This derivation is more correct in comparison with previous works which used only single-diagonal matrix. It is demonstrated that inverse problem procedure is nothin...
متن کاملMatrix representation of a sixth order Sturm-Liouville problem and related inverse problem with finite spectrum
In this paper, we find matrix representation of a class of sixth order Sturm-Liouville problem (SLP) with separated, self-adjoint boundary conditions and we show that such SLP have finite spectrum. Also for a given matrix eigenvalue problem $HX=lambda VX$, where $H$ is a block tridiagonal matrix and $V$ is a block diagonal matrix, we find a sixth order boundary value problem of Atkin...
متن کاملA Posteriori Eigenvalue Error Estimation for the Schrödinger Operator with the Inverse Square Potential
We develop an a posteriori error estimate of hierarchical type for Dirichlet eigenvalue problems of the form (−∆ + (c/r))ψ = λψ on bounded domains Ω, where r is the distance to the origin, which is assumed to be in Ω. This error estimate is proven to be asymptotically identical to the eigenvalue approximation error on a family of geometrically-graded meshes. Numerical experiments demonstrate th...
متن کاملRETRACTED On construction of a complex finite Jacobi matrix from two spectra
This paper concerns with the inverse spectral problem for two spectra of finite order complex Jacobi matrices (tri-diagonal symmetric matrices with complex entries). The problem is to reconstruct the matrix using two sets of eigenvalues, one for the original Jacobi matrix and one for the matrix obtained by replacing the last diagonal element of the Jacobi matrix by some other number. The unique...
