摘要
本文对一般形式的线性Fredholm积-微分方程推导出迭代Galerkin解及其导数的渐近展式,从而得到了迭代解的外推估计,同时还获得了理想的校正结果.
In this paper, an asmptotic error expansion for the iterated Galerkin approximation (along with its derivative) to a larger class of linear Fredholm integro-differential equations is derived, and thus the extrapolation estimate is obtained. Moreover, the ideal multilevel correction estimate is given.
