摘要
用Nystym方法对对数型非光滑核的抛物型积分微分方程进行离散,然后利用三步广义共轭余量法迭代求解,其误差为)(lo;迭代过程中的矩阵与向量的乘积则采用快速多极方法,使得此计算时间复杂度由()2nO降至O(n).
Firstly, the integro-differential equation of parabolic type with log-type nonsmooth kernel is discretized by Nysty鰉 method,then the lineal equations are solved by three-step General Conjugate Residual method , and as a result its error is[(\))960(\()]lo.In the iteration,the application of the fast multipole method to the matrix-vector mulplication renders the time complexity from ()2nO to ()nO.
