非奇H阵行列式的下界和‖A-1B‖∞的估计
LOWER BOUNDS OF DETERMINANT FOR AN H-MATRIX AND ESTIMATES OF ‖A-1B‖∞
【摘要】 给出了具有广泛实际背景的非奇H矩阵(严格对角占优阵,不可约对角占优阵等均为非奇H阵)行列式的下界估计,且在A为非奇H阵情况下给出,‖A-1B‖∞的估计。
【Abstract】 The lower bounds of determinant for an H-matrix are given, and more concrete estimates of upper bounds of ‖A-1B‖∞ than those in previous paper are yet given when A is an H-matrix.
