| Abstract | |
We classify the global phase portraits in the Poincare disc of the differential systems x = y + x f(x,y), y = x + y f(x,y), where f(x,y) is a homogeneous polynomial of degree 3. These systems have a uniform isochronous center at the origin. This paper together with the results presented in {[}9] completes the classification of the global phase portraits in the Poincare disc of all quartic polynomial differential systems with a uniform isochronous center at the origin.
