摘要
改进了[1—2]和[9]的结果,给出了一类三次样条插值法,建立了积分方程的三次样条配置方程,讨论了配置解的存在唯一性及稳定性,得到了三次样条插值及相应积分方程配置解的误差估计及误差的渐近表达式。
In this paper, the results of[1-2] and [9] are improved. A method for a class of cubic interpolation spline is given, and the collocation equations of the cubic spline for integral equations is developed. The existence, the uniqueness, and the stability of collocation solution are discussed. The asymptotic expansion formula of errors for the cubic interpolation spline and the collocation solution are obtained.
