The Uniform Isochronous Centers with Homogeneous Nonlinearities of Degree 5

Journal of Dynamical and Control Systems
The interest in studying the uniform isochronous centers goes back to C. Huygens in the XVII century. Since then, many papers have been published on this subject. In particular, the phase portraits of the polynomial uniform isochronous center up to degree four have been classified.

Global Phase Portraits of Uniform Isochronous Centers System of Degree Six with Polynomial Commutator

Acta Mathematicae Applicatae Sinica, English Series
This paper provides an in-depth study of the global phase portraits of uniform isochronous centers in systems of degree six, characterized by a polynomial commutator. The authors focus on systems of the form \[ \dot{x} = -y + xf(x, y) \text{ and } \dot{y} = x + yf(x, y), \] where \( f(x, y) = x\sigma(y) \), exploring the geometric implications of ...

On the number of limit cycles coming from a uniform isochronous center with continuous and discontinuous quartic perturbations

Journal of Applied Analysis, 2023
Abstract In this paper, we study the number of limit cycles bifurcated from the periodic orbits of a cubic uniform isochronous center with continuous and discontinuous quartic polynomial perturbations. Using the averaging theory of first order for continuous and discontinuous differential systems and comparing the obtained results, we ...
