严格对角占优M-矩阵的逆矩阵无穷大范数上界的序列

The sequence of upper bounds for the infinity norms of inverses of strictly diagonally dominant M-matrices

利用严格对角占优M-矩阵的逆矩阵元素的上界序列,得到了1A收敛的上界序列和q(A)收敛的下界序列。这些新的序列提高了现有关于该类问题的研究结果。

The use of the sequence of upper bound the inverse of elements of strictly diagonally dominant M-matrix, obtain the upper bound of the convergence of a sequence of 1A,and the convergence of the sequence of lower bounds of q(A). These new sequences to improve the results of existing research on this kind problem.
