复半正定矩阵的标准形及行列式模的不等式

THE CANONICAL FORM AND INEQUALITIES OF THE NORM OF DETERMINANT FOR COMPLEX SEMIDEFINITE POSITIVE MATRIX

建立了复半正定矩阵的复相合标准形 ,由此得到复半正定矩阵行列式模的两个重要不等式 ,推广了Ostrowskii_Taussky不等式及李俊杰 (1995 )

The canonical form for complcx semidefinite positive matrix under complex congruence is established, therefore two important inequalities of the norm of determinant are obtaincd. Ostrowskii_Tausky's inequality and the corresponding results of Prof Li Junjie's(1995) are generalized.
