ІНТЕГРАЛЬНІ ПРЕДСТАВЛЕННЯ ПОЛІГАРМОНІЙНИХ ОПЕРАТОРІВ

Анотація. У дослідженні представлено оптимальні математичні моделі в контексті задач системного аналізу. А саме, застосовано нетривіальні граничні умови до задачі про інтегрування полігармонійних рівнянь у полярних координатах. Функцію, тригармонійну в одиничному крузі, подано у вигляді інтеграла саме з дельтаподібним ядром. Розглянуто питання про існування структурного зв’язку між розв’язками тригармонійних рівнянь у полярних координатах та додатними операторами, які є розв’язками інших диференціальних рівнянь у частинних похідних. Показано, що тригармонійний інтеграл Пуассона для одиничного круга можна подати як середнє значення розв’язку рівняння Лапласа в полярних координатах.

Ключові слова: ряд Фур’є, тригармонійне рівняння, одиничний круг, тригармонійний інтеграл Пуассона, оператор Абеля–Пуассона.
