“…In [36] the regularized trace method was used to compute the eigenvalues of a perturbed semibounded discrete operator Т + Р, where Т is an operator semibounded from below and P is a bounded operator both defined in a separable Hilbert space H; moreover, Т has eigenvalues of arbitrary multiplicity. The algo rithm for computing the eigenvalues of Т + Р was based on solving a system of q linear algebraic equations, where q is the multiplicity of the eigenvalue β m of T. Some of the computed eigenvalues β m were presented in tables up to seven decimal digits.…”

“…Кравченко, И.И. Кинзиной [1,[3][4][5][6][7][8][9] привела к созданию и обоснованию метода вычисления собственных чисел возмущенного оператора, а также созданию численных алгоритмов, реализующих данный метод. Идея метода состоит в следующем.…”
