We consider in this article 1 a lopsided quartic polynomial vector field We first compute the first non-zero derivative of the return map r → L(r, ε). We study then the necessary and sufficient conditions for the existence of a center.

The computation of period constants is a way to study isochronous center for polynomial differential systems. In this article, a new method to compute period constants is given. The algorithm is recursive and easy to realize with computer algebraic system. As an application, we discuss the center co
This paper shows the su cient conditions for the existence of a Lyapunov function in the class of quasi-polynomial dynamical systems. We focus on the cases where the system's parameters are numerically speciÿed. A numerical algorithm to analyze this problem is presented, which involves the resolutio
