摘    要:本文对一类积-微分方程推得了其有限元迭代解及其导数的多项渐近展式,从而可对其反复地进行外推,以求得其具有足够收敛阶的近似解。

关 键 词:积-微分方程  迭代解  有限元

Abstract:In this paper,the asymptotic expansions with more termsfor the k-degree iterated Galerkin approximation solution along with itsderivatives of integro-differential equations are obtained,thus the ex-trapolation to it can be done repeatedly in order to get an approximationsolution which has enough high accuracy.
Keywords:integro-differential equations  iterated solution  asymp-totic expansions  extrapolation estimate
