Abstract
In this paper we classify the centers localized at the origin of coordinates, the cyclicity of their Hopf bifurcation and their isochronicity for the polynomial differential systems in ℝ of degree d that in complex notation z = x + iy can be written as where j is either 0 or 1, d is an arbitrary odd positive integer greater than or equal to five, λ ε ℝ, and A,B,C,D ε ℂ. Note that if d = 5 we obtain special families of quintic polynomial differential systems. © 2009 Birkhäuser Verlag Basel/Switzerland.
