No. 17 (234), issue 8Pages 46 - 51 NUMERIC METHOD OF FINDING THE EIGENVALUES FOR THE DISCRETE LOWER SEMIBOUNDED OPERATORS
S.I. Kadchenko, L.S. RyazanovaIn the work the effective method of finding the eigenvalues of the perterbed discrete lower semibounded operators, when the eigenvalues of not perterbed operators have an arbitary multiplicity, is developed. New results, allowing to apply this method by experts, having basic knowledge in the area of the spectral theory of operators are received.
