A Positive Definite Condition for a Block-Matrix and Its Application to Linear Ordinary Differential Equations
He Suyang (Department of Mathematics, Anhui Normal University, Wuhu, Anhui)
Let be a real symmetric block-matrix with A and B positive definte. Then M is positive definte if and only if. An application for this result to the stability of constant coefficient linear system is presented.
