Further Researches on Generalized Positive Definite Matrices
【摘要】 基于正定矩阵的几个定义,首先给出了广义正定矩阵的一些新性质,其次研究了广义正定矩阵与H-矩阵、M-矩阵的关系,推广和改进了文献中的有关行列式不等式.
【Abstract】 In this paper,some new basic properties of generalized positive definite matrices are obtained.Based on them,results about relationship between generalized positive definite matrices and H-matrices,M-matrices are presented.Finally,the corresponding determinant inequalities are generalized and improved.
