Integrable Abel equations and Vein's Abel equation [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2016
We first reformulate and expand with several novel findings some of the basic results in the integrability of Abel equations. Next, these results are applied to Vein's Abel equation whose solutions are expressed in terms of the third order hyperbolic ...

A complete and partial integrability technique of the Lorenz system

open access: yesResults in Physics, 2018
In this paper we deal with the well-known nonlinear Lorenz system that describes the deterministic chaos phenomenon. We consider an interesting problem with time-varying phenomena in quantum optics. Then we establish from the motion equations the passage

Planar nonautonomous polynomial equations V. The Abel equation [PDF]

open access: yesOpuscula Mathematica, 2013
We give a full description of the dynamics of the Abel equation \(z'=z^3+f(t)\) for some special complex valued \(f\). We also prove the existence of at least three periodic solutions for equations of the form \(z'=z^n+f(t)\) for odd \(n \geq 5\).

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.
