关于“四元数自共轭矩阵与行列式的几个定理”的注记

本刊1985年第4期发表郝稚传的“四元数自共轭矩与行列式的几个定理”(称为〔1〕)的文章的主要工作分为两部分。〔1〕在英文摘要中写到:“(i)This essay has improvedthe conclusion of theorem 8 and theorem 9 in 〔2〕”即〔1〕之第一部分工作在于改进了〔2〕的定理8、9的结果,其根据就是〔1〕的定理1、2.〔1〕称定理1—若

A Note on "Several Theorems of Self-Conjugate Quaternions Matrices and Determinants"

1] said that theorem 1 and theorem 2 of 1] have improved the conclusion of theorem 8 and theorem 9 in 2].We point out this way of say ing is incorrect, and the conclusion of theorem 8 and theorem 9 in 2 ] is not improved if we hold that A and B are any self-conjugate quaternions semipositive definite and positive definite matrix.
