Л. М. Новицкий

2012, выпуск 2, С. 255–261


Аннотация
Общее линейное интегральное уравнение 3-го рода в $L^2(Y,\mu)$ сводится унитарным преобразованием к эквивалентному интегральному уравнению 1-го или 2-го рода в $L^2(\mathbb{R})$ с ядром, представляющим собой линейный пучок ограниченных, бесконечно дифференцируемых бикарлемановских ядер мерсеровского типа.

Ключевые слова: линейные интегральные уравнения 1, 2 и 3-го рода, унитарный оператор, оператор умножения, биинтегральный оператор, бикарлемановское ядро, ядро Гильберта–Шмидта, билинейные разложения ядер
