摘要: 利用复插值样条函数,给出了定义于光滑封闭曲线上一般的正则型奇异积分方程的样条间接逼近解法,证明了一致收敛性.对于其中的一类奇异积分方程,还给出了近似解和误差估计.

Abstract: In this paper, using the interpolating complex cubic splines, we give a method of indirect approximate solution for singular integral eguations of normal type defined on a smooth closed contour, discuss the property of uniform convergence. We also estimate the errors for a kind of singular integral equations.
