Solution of the inverse spectral problem for differential operators on a finite interval with complex weights
[Решение обратной спектральной задачи для дифференциальных операторов на конечном интервале с комплексными весами]
Исследуются несамосопряженные обыкновенные дифференциальные операторы второго порядка на конечном интервале с комплексными весами. Установлены свойства спектральных характеристик и изучается обратная задача восстановления операторов по их спектральным характеристикам. Для этого класса нелинейных обратных задач получен алгоритм для построения глобального решения. Для исследования этого класса обратных задач используется развитие идей метода спектральных отображений.
