Figure 1From: Global Hopf bifurcation for three-species ratio-dependent predator-prey system with two delays The trajectories of system ( 5.1 ) with \(\pmb{\tau _{1}=0}\) , \(\pmb{\tau_{2}=1.1<\tau_{2_{10}}=31.1328}\) . The positive equilibrium \(E^{*}\) is asymptotically stable. The initial value is \((4,3.2,1)\).Back to article page
