Abstract
In this paper, some necessary and sufficient conditions for the existence of the positive definite solutions for the matrix equation X + A^*^X^โฮฑ^A = Q with ฮฑ โ (0, โ) are given. Iterative methods to obtain the positive definite solutions are established and the rates of convergence of the considered methods are obtained. Copyright ยฉ 2006 John Wiley & Sons, Ltd.

It is pointed out that the main results in a recent paper by Kano (1987) have previously been published in the literature. IN KANO (1987), necessary and sufficient conditions are given for the existence and uniqueness of positive definite solutions to the algebraic Riccati equation and asymptotic s
Algebraic matrix Riccati equations are considered which arise in the optimal filtering as well as in control problems of continuous time-invariant systems. A necessary and sufficient condition is established for the existence of unique positivedefinite solutions and the asymptotically stable closed-
