A new method to determine isochronous center conditions for polynomial differential systems.
The authors give a new algorithm to compute period constants of complex polynomial systems, and the set of period constants of real polynomial systems is a spacial case of it. The algorithm is recursive and avoids complex integrating operations and solving equations. As an example of the algorithm, center conditions and isochronous center conditions for a class of higher degree systems have been discussed.
