Transformation of the Eilenberger Equations of Superconductivity to a Scalar Riccati Equation
, 1998 A new parametrisation of the Eilenberger equations of superconductivity in terms of the solutions to a scalar differential equation of the Riccati type is introduced. It is shown that the quasiclassical propagator, and in particular the local density of states, may be reconstructed, without explicit knowledge of any eigenfunctions and eigenvalues, by ...

Oscillation for forced second-order nonlinear dynamic equations on time scales
Electronic Journal of Differential Equations, 2006 By means of Riccati transformation techniques, we present oscillation criteria for forced second-order nonlinear dynamic equations on time scales. These results are based on the information on a sequence of subintervals of $[a, infty)$ only, rather than ...

In this paper we revisit the problems of passivity and bounded realness preserving model reduction by balanced truncation. In the behavioral framework, these problems can be considered as special cases of balanced truncation of strictly half line ...

Derivation of a Riccati Form equation from the Klein-Gordon equation and its solution
This work was conducted independently. In this article, we explore the transformation of the Klein-Gordon equation, a second-order relativistic partial differential equation, into a Riccati equation.

A Result on Output Feedback Linear Quadratic Control [PDF]
In this note we consider the static output feedback linear quadratic control problem.We present both necessary and sufficient conditions under which this problem has a solution in case the involved cost depend only on the output and control variables ...

ON DETERMINATION OF SOLUTION OF UNILATERAL QUADRATIC MATRIX EQUATION
Міжнародний науково-технічний журнал "Проблеми керування та інформатики"Usually used for finding the solutions of discrete algebraic Riccati equation, the method of doubling transformation is generalized on the case of unilateral quadratic matrix equation. On the examples, the efficiency of the offered algorithm of solution

An analytic Riccati solution for two-target discrete-time control [PDF]
, 2000 This paper analytically solves the Riccati equation of discrete optimal control with two targets and one tool. This is accomplished by reducing the problem to a nonlinear univariate dynamic equation; this can be solved by a suitable transformation of ...

Oscillation of second-order nonlinear impulsive dynamic equations on time scales
Electronic Journal of Differential Equations, 2007 In this article, we study the oscillation of second-order nonlinear impulsive dynamic equations on time scales. Using Riccati transformation techniques, we obtain sufficient conditions for oscillation of all solutions.
