The dynamics of some cubic vector fields with a center
V. Županović
Abstract
We study planar cubic vector fields
\[V_H=yP_2\frac{\partial}{\partial x}-x Q_2\frac{\partial}{\partial y}\] with a center, having Darboux first integral $H=P_1^2Q_3$. We give the bifurcation diagram of the phase portraits of the vector fields, in 2-dimensional parameter space.
