摘要
给出了求解带不可微项方程的一种迭代格式,利用优序列技巧,在γ-条件下,给出了该迭代格式的存在性与收敛性定理,并给出了误差估计.得到的结果为:当判据a≤3-L-2 2-L时,该迭代格式所产生的向量序列{zn}与{wn}均收敛于方程f(z)+g(z)=0的唯一解z*,且有误差估计为:|z*-zn|≤t*-tn,|z*-wn|≤t*-sn.
In this paper , an iterative method is given to solve the equations with non-differential terms . Under the γ - condition , the existence and theorem are proved and the error estimation is obtained by the technique of major function sequences . The result is as follwing: if a ≤ 3 - L - 2 √2-L, then the sequences { zn }, { wn } produced by the iterate scheme given in the paper, converge to the solution off(z) + g(z) =0. The error estimation is as follwing: |z^* - zn |≤ t^* -tn,|z^* -wn|〈t^* -sn.
