摘要Abstract:
We are interested in finding stable large periodic orbits of an ODE system that describes the dynamics of two predators competing for the same prey. The prey population grows logistically in the absence of predation, and the predators feed on the prey with Holling’s type-II response. We first briefly explain a characterization of parameter regions that may support coexistence states. Then we explain how stable large periodic orbits are triggered by perturbing an elliptic Hopf bifurcation point without parameters. For this aim, we prove that the ODE system admits an elliptic Hopf bifurcation and the existence of periodic orbits are ensured by the averaging method. This is an ongoing research with A. López Nieto, P. Lappicy, H. Stuke, and N. Vassena.
