Dynamic behaviour of an eco-epidemiological model of fractional-order with a fear effect

In this paper, we propose a fractional-order prey-predator model with fear effects on the dynamic behavior of the populations. The model is used as a functional response of Holling type II in a non-delayed model. First, we prove several important results such as the existence, uniqueness, and boundedness of the solutions to the fractional-order dynamical system. Next, we discuss both the local and global stabilities of the fractional-order prey-predator model. The occurrence of Hopf bifurcation for fractional order is examined. Finally, the analytical solutions are confirmed through numerical simulations.
