Newton’s method for a rational matrix equation occurring in stochastic control. (English) Zbl 0982.65050
The paper deals with a general class of rational matrix equations containing the continuous and discrete Riccati equations. The authors present a unifying framework for analysis of this class of equations based on theory of resolvent positive operators. Solvability starting at an arbitrary stabilizing matrix is shown.
