Finite cyclicity of some graphics through a nilpotent point of saddle type inside quadratic systems

Christiane Rousseau, Chunhua Shan, Huaiping Zhu

In this paper we show the finite cyclicity of the two graphics $(I_{12}^{1})$ and $(I_{13}^{1})$ through a triple nilpotent point of saddle type inside quadratic vector fields. These r…
