Special factorization and Riccati integral equations [PDF]

open access: yes, 1984
A class of operator Riccati integral equations is associated with a factorization problem in a certain Banach algebra. Recent results concerning factorization in this algebra are used to obtain existence, uniqueness, and continuous dependence results for

Oscillation of third-order neutral differential equations with damping and distributed delay

open access: yesAdvances in Difference Equations, 2019
The present paper focuses on the oscillation of the third-order nonlinear neutral differential equations with damping and distributed delay. The oscillation of the third-order damped equations is often discussed by reducing the equations to the second ...

Lie and Riccati Linearization of a Class of Liénard Type Equations

open access: yesJournal of Applied Mathematics, 2012
We construct a linearizing Riccati transformation by using an ansatz and a linearizing point transformation utilizing the Lie point symmetry generators for a three-parameter class of Liénard type nonlinear second-order ordinary differential equations ...

Generalized Riccati difference and differential equations [PDF]

open access: yes, 1996
In this paper we investigate generalized Riccati differential and difference equations obtained from standard Riccati equations by adding a semidefinite perturbation term. For such equations we give results on the monotonic dependence of the solutions on

Schwarzian derivative in higher-order Riccati equations

open access: yes, 2022
The Sturm-Liouville equation represents the linearized form of the first-order Riccati equation. This provides an evidence for the connection between Schwarzian derivative and this first-order nonlinear differential equation.

A Note on the Riccati Differential Equation

open access: yesJournal of Mathematical Analysis and Applications, 1995
The author treats the Riccati differential equation \[ w'= a(z)+ b(z) w+ c(z) w^ 2,\tag{1} \] where \(z\), \(w\) are complex variables and \(a(z)\), \(b(z)\) and \(c(z)\) are meromorphic on the whole \(z\)-plane. It is known that by a suitable transformation (1) can be transformed into the form (2) \(w'= A(z)+ w^ 2\), where \(A(z)\) is meromorphic on ...
