摘要
研究了复正规矩阵的亚正定性,给出了复矩阵之积为复亚正定矩阵的一系列充要条件,获得了一些新的结果;改进并推广了Ky Fan Taussky定理、Fejer定理等.
The properties of metapositive definite of complex normal matrices are discussed, and a series of necessary and sufficient conditions under which of the product two complex matrices will be a complex metapositive definite matrix is given, and some new results are gained. In addition, several theorems,such as Ky Fan Taussky theorem,Fejer theorem, etc. are generalized and improved.
