Аппроксимационное Решение Интегральных Уравнений Фредгольма И Вольтерра Второго Рода Методом S-Преобразований

Аппроксимационное Решение Интегральных Уравнений Фредгольма И Вольтерра Второго Рода Методом S-Преобразований

Abstract

Аппроксимационно-операционный подход применен к решению интегральных уравнений Фредгольма и Вольтерра второго рода. Показано, что аппроксимация ядер интегральных уравнений как сигналов, зависящих от двух аргументов, обобщенными полиномами на основе двумерных базисных функций блочно-импульсного типа позволяет алгебраизировать интегральные уравнения. Приведены примеры, иллюстрирующие применение подхода в программной среде системы Mathematica® --- О. V. Vasyliev, V. V. Vasylyev, L. A. Simak Approximative solution of integral Fredholm and Volterra equations of the second kind by Stransform Approximative-operational approach is applied to the solution of integral equations of Fredholm and Volterra second kind. It is shown that the approximation of the kernels of integral equations as a signals dependent of two arguments, via generalized polynomials on the basis of two-dimensional basis functions of block-pulse type allows to obtain the algebraizable form of integral equations. Computer experiments are completed via programming environment of Mathematica ®.
