摘要

In this work, we generalize the numerical method discussed in [Z. Avazzadeh, M. Heydari, G.B. Loghmani, Numerical solution of Fredholm integral equations of the second kind by using integral mean value theorem, Appl. math, modelling, 35 (2011) 2374-2383] for solving linear and nonlinear Fredholm integral and integro-differential equations of the second kind. The presented method can be used for solving integral equations in high dimensions. In this work, we describe the integral mean value method (IMVM) as the technical algorithm for solving high dimensional integral equations. The main idea in this method is applying the integral mean value theorem. However the mean value theorem is valid for multiple integrals, we apply one dimensional integral mean value theorem directly to fulfill required linearly independent equations. We solve some examples to investigate the applicability and simplicity of the method. The numerical results confirm that the method is efficient and simple.

Loghmani,第二类Fredholm积分方程的数值解,使用积分平均值定理Appl。 Math,modelling,35(2011)2374-2383],用于求解第二类线性和非线性Fredholm积分方程和积分微分方程。所提出的方法可以用于求解高维积分方程。在这项工作中,我们将积分均值方法(IMVM)描述为解决高维积分方程的技术算法。该方法的主要思想是应用积分平均值定理。但是,平均值定理对多个积分有效,我们直接应用一维积分平均值定理来满足所需的线性独立方程。我们解决了一些例子,以研究该方法的适用性和简便性。数值结果证实了该方法的有效性和简便性。
