Dynamic complexity of a slow-fast predator-prey model with herd behavior

The complex dynamics of a slow-fast predator-prey interaction with herd behavior are examined in this work. We investigate the presence and stability of fixed points. By employing the bifurcation theory, it is shown that the model undergoes both a period-doubling and a Neimark-Sacker bifurcation at the interior fixed point. Under the influence of period-doubling and Neimark-Sacker bifurcations, chaos is controlled using the hybrid control approach. Moreover, numerical simulations are carried out to highlight the model's complexity and show how well they agree with analytical findings. Employing the slow-fast factor as the bifurcation parameter shows that the model goes through a Neimark-Sacker bifurcation for greater values of the slow-fast factor at the interior fixed point. This makes sense because if the slow-fast factor is large, the growth rates of the predator and its prey will be about identical, automatically causing the interior fixed point to become unstable owing to the predator's slow growth.

Automated summary

This paper examines the complex dynamics of a slow-fast predator-prey interaction with herd behavior. Through bifurcation theory, it is shown that the model experiences both period-doubling and Neimark-Sacker bifurcations at the interior fixed point. Chaos is controlled using the hybrid control approach under the influence of these bifurcations. Numerical simulations highlight the complexity of the model and demonstrate agreement with analytical findings. Using the slow-fast factor as the bifurcation parameter reveals that the model undergoes a Neimark-Sacker bifurcation for larger values of the slow-fast factor at the interior fixed point.
