摘要

本文给出了求解二维第二类Fredholm和Volterra积分方程的一种有效方法。应用切比雪夫多项式近似求解这些积分方程。该方法将积分方程转化为具有未知切比雪夫系数的代数方程。通过数值算例验证了该方法的高精度。数学学科分类:65R20、41A50、41A55、65M70。

Chebyshev polynomials for solving two dimensional linear and nonlinear integral equations of the second kind

In this paper, an efficient method is presented for solving two dimensional Fredholm and Volterra integral equations of the second kind. Chebyshev polynomials are applied to approximate a solution for these integral equations. This method transforms the integral equation to algebraic equations with unknown Chebyshev coefficients. The high accuracy of this method is verified through some numerical examples. Mathematical subject classification: 65R20, 41A50, 41A55, 65M70.
