Figure 4From: Global Hopf bifurcation for three-species ratio-dependent predator-prey system with two delays The trajectories of system ( 5.1 ) with \(\pmb{\tau _{1}=15}\) , \(\pmb{\tau_{2}=1.1}\) . The positive equilibrium \(E^{*}\) is asymptotically stable. The initial value is \((4,3.2,1)\).Back to article page
