Abstract

The main focus of this paper is the investigation of simultaneous existence of centers in symmetric planar polynomial differential systems. There are presented necessary and sufficient conditions for the existence of a bi-center of four families of real cubic symmetric systems. Furthermore, the conditions for the isochronicity of such bi-centers are obtained. (C) 2020 Elsevier Ltd. All rights reserved. (AU)
