We will also use our results together with some old results to give new proofs or shorter proofs of some known theorems such as RadJavi's theorem about characterization of products of four Hermitlan matrices and Wu's theorem about products of four positive semidefinite matrices.58 pagesAvailable to the World Wide WebThesis
