摘要:

运用α-链对角占优矩阵的理论及Holder不等式的放缩技巧, 得到非奇异H-矩阵的几个新判据, 推广并改进了已有的对H-矩阵的判定方法, 并用数值算例说明了所给判定方法的有效性和优越性.

关键词: 非奇异H-矩阵, 对角占优矩阵, 正对角矩阵, &alpha, -链对角占优矩阵

Abstract:

By using the theory of α-chain diagonally dominant matrices and some techniques for Hlder inequalities, we obtained some new criteria for nonsingular H-matrices, and thus the corresponding results improved and generalized the existing determination methods for H-matrices. The validity and superiority of the determination methods were illustrated by numerical examples.

Key words: nonsingular H-matrix; diagonally dominant matrix; positive diagonal matrix; &alpha, -chain diagonally dominant matrix
