摘要
研究了半正定复方阵的性质及行列式理论,取得了一些新的结果,推广和改进了Minkowski、Ky-Fan、Ostrowski-Taussky等著名行列式不等式,扩大了Minkowski不等式的指数范围,削弱了华罗庚不等式的条件.
The properties and determinant theories of positive semidefinite complex square matrices are discussed,some new results are given,and some wellknown determinant inequalities such as those of Minkowski,Ky Fan,OstrowskiTaussky are generalized and improved.In addition,the condition of Hua Luogeng inequality is weakened.
