Calculation of Spectral Characteristics of Perturbed Self-Adjoint Operators by Methods of Regularized Traces

Publikováno v: Journal of Mathematical Sciences. 241:570-588

We discuss basic theoretical principles underlying new numerical methods of calculation of eigenvalues and eigenfunctions of discrete operators semi-bounded from below. We present algorithms of finding spectral characteristics by methods of regulariz

The numerical method of solving of inverse spectral problems generated by perturbed self-adjoint operator

Autor: S. I. Kadchenko, A. I. Kadchenko, G. A. Zakirova

Publikováno v: 2016 2nd International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM).

The interest in developing methods for solving inverse spectral problems is stimulated by extension of their application in various fields of science and technology. For example, the spectral problems find their growing application in the theory of d

Computation of eigenvalues of perturbed discrete semibounded operators

Autor: I. I. Kinzina, S. I. Kadchenko

Publikováno v: Computational Mathematics and Mathematical Physics. 46:1200-1206

To compute the eigenvalues of a perturbed discrete semibounded operator, systems are obtained for the first time in which the number of equations is equal to the multiplicity of the corresponding eigenvalues of the unperturbed operator.
