摘要/Abstract

摘要： 讨论Ostrowski-Taussky不等式在广义正定矩阵上的推广. 这些推广的不等式改进了Johnson, Horn，游兆永和孙建东的相应结果.

关键词: Ostrowski-Taussky不等式, 广义正定矩阵, 最小指数

Abstract: In this paper, we discuss the extension of Ostrowski-Taussky inequalit y over generalized positive definite matrices. The corresponding results of Horn R A, Johnson CR, You Zhao-yong and Sun Jian-dong are improved by the application of these generalized inequalities.

Key words: Ostrowski-Taussky inequality, generalized positive definite matrices, smallest experent
