On Chouikha's isochronicity criterion

Jean-Marie Strelcyn

Recently A.R.Chouikha gave a new characterization of isochronicity of center at the origin for the equation $x " + g (x) = 0$ , where $g$ is a real smooth function defined in some neighbo…

Isochronicity conditions for some planar polynomial systems II

Magali Bardet, Islam Boussaada, A. Raouf Chouikha +1

We study the isochronicity of centers at $O \in R^{2}$ for systems $x ˙ = - y + A (x, y), y ˙ = x + B (x, y),$ where $A, B \in R [x, y]$ , which can be reduced to the Liéna…
