ACCELERATION OF CONVERGENCE FOR GALERKIN APPROXIMATION TO FREDHOLM INTEGRO-DIFFERENTIAL EQUATIONS
Fredholm积-微分方程Galerkin解的加速收敛分析

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.
