摘要
设A,B是两个Hermite半正定矩阵或Hermite正定矩阵,研究了A,B的组合的迹的不等式问题.得到了Hermite半正定矩阵和Hermite正定矩阵的组合的迹的几个重要不等式,推广了相关文献的结果.
A and B are two Hermite positive semidefinite matrices or two Hermite positive definite matrices.In this paper,the inequalities of the trace of the combination of A and B are studied.Some important inequalities of the trace of the combination of the Hermite semi positive definite matrix and the Hermite positive definite matrix are obtained,and the results of the related literature are extended.
