Abstract

We consider the generic cuartic differential system. In [7] it was proven that the class of differential cuartic systems that have the invariant straight line at the infinity of maximal multiplicity is affine equivalent with the system x¤ = −3x + ay4 , y¤ = y, a > 0. In this paper, by using several techniques, we obtain its phase portrait on Poincaré disk.
