| Abstract: | This paper investigates the isochronous center problem for a class of quintic Z6-equivalent polynomial differential system,derives the recursive formulae to compute the period constants at the origin,and concludes that the singular points of the system can not be isochronous center. |

| Keywords: | quintic Z6-equivalent polynomial system period constant isochronous center |
