积-微分方程配置解的天然超收敛性
THE NATURAL SUPERCONVERGENCE OF COLLOCATION APPROXIMATION FOR INTEGRO-DIFFERENTIAL EQUATIONS
【摘要】 讨论了线性Fredholm积-微分方程的配置方法,获得了配置解本身(不用迭代)的超收敛估计和外推估计.
【Abstract】 We discuss the collocation method for linear fredholm integro-differential equation in this paper. A superconvergence estimate and a extrapolation estimate of the collocation approximation itself (not iterated)are obtained.
