Abstract:In this paper, we give the new extiension of the concept of real extended positive definite matrices and its basic properties, discuss the algebraic structure of extended positive definite matrices under the concept and some usual definitions, obtain a new depiction of unsymmetrical positive definite matrices product, and extend the given forms of Minkowski, Ostrowski-Taussky matric inequalities further by using the obtained property of extended positive definite matrices.
Keywords:generalized positive matrices  matrices product  inequality
