On the Use of Low-Order Riccati-Equations in the Design of a Class of Feedback Controllers and State Estimators [PDF]
Modeling, Identification and Control, 1980 This paper describes a method for designing optimal feedback controllers with stability requirements using low-order Riccati equations. For originally stable systems the Riccati equation will be of first or second order, depending upon whether the ...

The Riccati Equation in Mathematical Finance
Journal of Symbolic Computation, 2002 The authors summarize the relevant literature on closed-form solutions to the Riccati equation. They describe Kovacic's important contributions to the field. Next, they summarize some of the relevant aspects of the Cox-Ingersoll-Ross model. They describe in more detail the connection between the Riccati equation and practical implementation of the CIR ...
