In this work, we study the generic homogeneous polynomial differential system x˙ 1 = Pk(x1, x2), x˙ 2 = Qk(x1, x2) under the action of the center-affine group of transformations of the phase space, GL(2, R). We show that if the dimension of the
GL(2, R)− orbits of this system is smaller than four, then deg(GCD(Pk, Qk)) ≥ k−1. |
