Several Determinant Inequalities of meta-positive Definite and Sub-symmetric Matrix

Abstract:In this paper,we present several determฑinant inequalities of positive definite matrix which had been proved,Then we extend these determina。nt inequalities into meta-positive definite matrix through using three well-known inequalities and obtain some new results.

Keywords:determinant inequality;posiพtive definite matr♀ix;meta-positive definite matrix;sub-symmetric matrix.
