The concept of complex metapositive semidefinite matrix is given, its properties and determinant theories are discussed, and then the Schur theorem, Hua Luo-geng theorem, Minkowski inequality, Protruding property inequality and Ostrowski-Taussky inequality of Hermite matrices are generalized to more extensive compound matrix genus.
给出了复亚半正定矩阵的概念,研究了它的基本性质及行列式理论,将Hermite阵的Schur定理华罗庚定理Minkowski不等式凸性不等式Ostrowski-Taussky不等式推广到了较广泛的复矩阵类,扩大了Minkowski不等式的指数范围,削弱了华罗庚不等式的条件。
5) skewpositiove semidefinite matrix
斜亚半正定矩阵
6) minor positive (semi)definite matrix

补充资料:正定矩阵
设m是n阶实系数对称矩阵, 如果对任何非零向量
x=(x_1,...x_n) 都有 xmx^t>0,就称m正定。
正定矩阵在相似变换下可化为标准型, 即单位矩阵。
