Centers and Isochronous Centers of Newton Systems with Force Function Quadratic in Velocities

Differential Equations, 2019
Necessary and sufficient conditions are obtained for a center as well as an isochronous center of holomorphic Newton equations with force function quadratic in velocities.

Isochronicity of centers in some planar differential systems

SCIENTIA SINICA Mathematica, 2016
For planar differential systems the isochronicity of centers, as a continuation of the center problem, relates to the synchronism of periodic oscillations. In this paper we introduce recent results and basic methods on isochronicity of nondegenerate centers for planar differential systems including homogeneous systems, reversible systems, and ...

Commutators and linearizations of isochronous centers

2000
The authors study isochronous centers of some classes of plane differential systems. They consider systems with constant angular speed, both with homogeneous and nonhomogeneous nonlinearities, and show how to construct linearizations and first integrals to such systems, if a commutator is known.
