摘要
本文讨论了对求解差分方程有用的矩阵A^(-1)B的范数。胡家赣曾于1983年给出一个关于‖A^(-1)B‖的估计的定理。然而,这里给出一个比原来的证明更为简单的新的证明。
The norms of matrix A-1 B which are useful to solve difference equations are discussed in this paper. A theorem about the estimation of A-1B was given by Hu Jiaogan in 1983. Nevertheless, here the writer presents a new demonstration which is simpler than the former.
