摘要
We show the existence of a cubic system having at least one limit cycle bounded by two invariant parabolas. We will also obtain the necessary and sufficient conditions for the critical point in the interior of the bounded region to be a center. © 2009 Foundation for Scientific Research and Technological Innovation.
