Oppenheim Inequality on Extended Sub-positive Definite Matrix
Yang Zhong-peng · Journal of Jilin University(Science Edition) · 2006
The property of extended sub-positive definite matrix is studied further by means of the method of matrix analysis to obtain the lower estimated Oppenheim inequality of Hadamard multiplication determinant(belonging) to two extended sub-positive definite matrices under more general conditions and improve the past(results) in the adaptation range and estimated exactness.
