Isochronous Centers of Lienard Type Equations and Applications

A. Raouf Chouikha

In this work we study the equation $(E) x ¨ + f (x) x ˙^{2} + g (x) = 0$ with a center at 0 and investigate conditions of its isochronicity. When $f$ and $g$ are analytic (not n…

The Period Function of Second Order Differential Equations

A. Raouf Chouikha

We interest in the behaviour of the period function for equations of the type $u^{''} + g (u) = 0$ and $u^{''} + f (u) u^{'} + g (u) = 0$ with a center at the origin 0. $g$ is a function of cla…
