Abstract

We study a fractional-order delayed predator-prey model with Honing -Tanner-type functional response. Mainly, by choosing the delay time tau as the bifurcation parameter, we show that Hopf bifurcation can occur as the delay time tau passes some critical values. The local stability of a positive equilibrium and the existence of the Hopf bifurcations are established, and numerical simulations for justifying the theoretical analysis are also presented.
