摘要
讨论内分裂为不完全LU分解时,松弛型二级多分裂方法的收敛性.当系数矩阵为单调矩阵或H-矩阵时,证明了松弛因子的收敛域严格包含区间(0,1],改进了已有的结果.
It is studied the convergence of relaxed two-stage multisplitting iterative methods using incomplete factorization as inner iterations. When the coefficient matrix is either monotone or H-matrix, the convergent range of relaxation factor ω 〉 0 strictly includes the interval （0,1 ], which improving the known conclusions.
