The Cubic Polynomial Differential Systems with two Circles as Algebraic Limit Cycles [PDF]

open access: yesAdvanced Nonlinear Studies, 2018
In this paper we characterize all cubic polynomial differential systems in the plane having two circles as invariant algebraic limit cycles.

Algebraic theory of quantum synchronization and limit cycles under dissipation

open access: yesSciPost Physics, 2022
Synchronization is a phenomenon where interacting particles lock their motion and display non-trivial dynamics. Despite intense efforts studying synchronization in systems without clear classical limits, no comprehensive theory has been found. We develop

Dulac-Cherkas functions for generalized Liénard systems [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
Dulac-Cherkas functions can be used to derive an upper bound for the number of limit cycles of planar autonomous differential systems including criteria for the non-existence of limit cycles, at the same time they provide information about their ...

Polynomial differential systems with hyperbolic algebraic limit cycles

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
For a given algebraic curve of degree $n$, we exhibit differential systems of degree greater than or equal $n$, by introducing functions which are solutions of certain partial differential equations.

The algebraic curves of planar polynomial differential systems with homogeneous nonlinearities

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
We consider planar polynomial systems of ordinary differential equations of the form $\dot x = x + P_n(x,y)$, $\dot y = y + Q_n(x,y)$, where $P_n(x,y),\ Q_n(x,y)$ are homogeneous polynomials of degree $n$.

Rational Limit Cycles on Abel Polynomial Equations

open access: yesMathematics, 2020
In this paper we deal with Abel equations of the form d y / d x = A 1 ( x ) y + A 2 ( x ) y 2 + A 3 ( x ) y 3 , where A 1 ( x ) , A 2 ( x ) and A 3 ( x ) are real polynomials and A 3 ≢ 0 .

Non-algebraic limit cycles in Holling type III zooplankton-phytoplankton models

open access: yesCubo, 2021
We prove that for certain polynomial differential equations in the plane arising from predator-prey type III models with generalized rational functional response, any algebraic solution should be a rational function. As a consequence, limit cycles, which

Self-oscillations in a certain Belousov–Zhabotinsky model [PDF]

open access: yesMATEC Web of Conferences, 2022
We consider the dynamic properties of a system of three differential equations known as the oreganator model. This model depends on four external parameters and describes one of the periodic Belousov–Zhabotinsky reactions.

A class of nonlinear oscillators with non-autonomous first integrals and algebraic limit cycles

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
In this paper, we present a class of autonomous nonlinear oscillators with non-autonomous first integral. We prove explicitly the existence of a global sink which is, under some conditions, an algebraic limit cycle.

Limit Cycles of Polynomially Integrable Piecewise Differential Systems

open access: yesAxioms, 2023
In this paper, we study how many algebraic limit cycles have the discontinuous piecewise linear differential systems separated by a straight line, with polynomial first integrals on both sides.
