摘要
We classify the global phase portraits in the Poincare disc of the generalized Kukles systems (x) over dot = -y, (y) over dot = x + axy(6 )+ bx(3)y(4 )+ cx(5)y(2 )+ dx(7), which are symmetric with respect to both axes of coordinates. Moreover using the averaging theory up to sixth order, we study the cyclicity of the center located at the origin of coordinates, i.e. how many limit cycles can bifurcate from the origin of coordinates of the previous differential system when we perturb it inside the class of all polynomial differential systems of degree 7.
