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

On Solvability of the Sonin–Abel Equation in the Weighted Lebesgue Space

open access: yesFractal and Fractional, 2021
In this paper we present a method of studying a convolution operator under the Sonin conditions imposed on the kernel. The particular case of the Sonin kernel is a kernel of the fractional integral Riemman–Liouville operator, other various types of the ...

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.
