Positive definite solutions of a nonlinear matrix equation

In this paper we investigate the positive definite solutions of a special nonlinear matrix equation. Sufficient conditions for existence positive definite solutions of the described equation are derived. Two algorithms for numerical computing of these solutions are given.
