Abstract

© 2016 World Scientific Publishing Company. We consider the family of planar differential systems depending on two real parameters x = y, y = δ1x + δ2y + x3 - x2y. This system corresponds to the normal form for the 1:2 resonance which exhibits a heteroclinic connection. The phase portrait of the system has a limit cycle which disappears in the heteroclinic connection for the parameter values on the curve δ2 = c(δ1) = -1/5δ1 + O(δ12), δ1 < 0. We significantly improve the knowledge of this curve in a neighborhood of the origin.
