摘要
The matrix equation X + Sigma(n)(i=1) A(i)*X(-1) A(i) = I is studied. Some necessary and sufficient conditions for the existence of a positive definite solution of the matrix equation are obtained. Based on them, some properties of the the coefficient matrix are presented when the matrix equation has a positive definite solution.
