Polynomial Solutions of Equivariant Polynomial Abel Differential Equations [PDF]

open access: yesAdvanced Nonlinear Studies, 2018
Let a⁢(x){a(x)} be non-constant and let bj⁢(x){b_{j}(x)}, for j=0,1,2,3{j=0,1,2,3}, be real or complex polynomials in the variable x. Then the real or complex equivariant polynomial Abel differential equation a⁢(x)⁢y˙=b1⁢(x)⁢y+b3⁢(x)⁢y3{a(x)\dot{y}=b_{1}(

Periodic solutions of Abel differential equations

open access: yesJournal of Mathematical Analysis and Applications, 2007
For a class of polynomial non-autonomous differential equations of degree n, we use phase plane analysis to show that each equation in this class has n periodic solutions. The result implies that certain rigid two-dimensional systems have at most one limit cycle which appears through multiple Hopf bifurcation.

Abel differential equations admitting a certain first integral

open access: yesJournal of Mathematical Analysis and Applications, 2010
Abel differential equations in the form \[ \frac{dy}{dx}=a(x)y^3+b(x)y^2+c(x)y+d(x) \] are investigated in the present work. Conditions to have a certain first integral are given and these conditions establishing a bridge with Galois theory. The paper ends with two examples.

Universal Curves in the Center Problem for Abel Differential Equations [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2014
We study the center problem for the class $\mathcal E_\Gamma$ of Abel differential equations $\frac{dv}{dt}=a_1 v^2+a_2 v^3$, $a_1,a_2\in L^\infty ([0,T])$, such that images of Lipschitz paths $\tilde A:=\bigl(\int_0^\cdot a_1(s)ds, \int_0^\cdot a_2(s)ds\

Rational Limit Cycles of Abel Differential Equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
We study the number of rational limit cycles of the Abel equation x ′ = A ( t ) x 3 + B ( t ) x 2 , where A ( t ) and B ( t ) are real trigonometric polynomials. We show that this number is at most the degree of A ( t ) plus one.

The Unique Periodic Solution of Abel’s Differential Equation [PDF]

open access: yesJournal of Mathematics, 2020
In this paper, the existence of a periodic solution for Abel’s differential equation is obtained first by using the fixed-point theorem. Then, by constructing the Lyapunov function, the uniqueness and stability of the periodic solution of the equation are obtained.

Generalized Weierstrass Integrability of the Abel Differential Equations

open access: yesMediterranean Journal of Mathematics, 2013
We study the Abel differential equations that admits either a generalized Weierstrass first integral or a generalized Weierstrass inverse integrating factor.
