Необходимые и достаточные условия разрешимости обратной задачи для оператора Штурма-Лиувилля на конечном отрезке с неинтегрируемой особенностью внутри интервала

Abstract

В данной статье исследуется обратная задача спектрального анализа восстановления оператора Штурма-Лиувилля на конечном отрезке с неинтегрируемой особенностью типа Бесселя внутри интервала по заданным спектральным данным. Получена конструктивная процедура решения обратной задачи, доказана единственность восстановления оператора по заданным спектральным данным, а также получены необходимые и достаточные условия разрешимости данной обратной задачи.

The inverse spectral problem of recovering Sturm-Liouville operators on a finite interval with a nonintegrable Bessel-type singularity in an interior point from the given spectral data is studied. A corresponding uniqueness theorem is proved, a constructive procedure for the solution of the inverse problem is provided. Necessary and sufficient conditions for the solvability of the inverse problem are obtained.
