摘 要: 考虑核函数有弱奇性的第二类Fredholm积分方程的自适应数值解法, 讨论如何对核函数进行分片多项式插值逼近, 如何确定相关的参数,最后给出数值例子说明自适应解法的可行性. An adaptive method for the numerical solution of Fredholm integral equations of the second kind with weakly singular kernel is proposed. The approximation of weakly singular kernel functions with piece-wise interpolating polynomi- als and the determination of relevant parameters are discussed. Numerical examples are given to illustrate the feasibility of our adaptive method.
