Abstract: We study global dynamic behavior of a simple duopoly model already existing in literature, when a supercritical Neimark-Sacker bifurcation occurs. In particular, through the study of the critical lines, we provides numerical examples in order to explain the evolution of a closed invariant curve coexisting with periodic attractors into a ”weakly chaotic ring”.
