Алгебра 1. Лекция 4. Формальные степенные ряды и производящие функции
Jul 25, 2026LectureAlexey Ilyin
В этой лекции рассматриваются формальные степенные ряды как алгебраический объект. Вводятся операции сложения, умножения, а также аналоги производной и интеграла. Ключевая идея лекции — применение этого аппарата для решения линейно-рекуррентных соотношений с помощью производящих функций, что демонстрируется на классическом примере чисел Фибоначчи.
