Figure 7From: Hybrid control of Hopf bifurcation in a Lotka-Volterra predator-prey model with two delays Behavior and phase portrait of a controlled system ( 1.3 ) with \(\pmb{\alpha= 1}\) , \(\pmb{\beta= 0.1}\) , \(\pmb{\tau_{1} = 0}\) , \(\pmb{\tau_{2} = 3.7 > \tau_{2}^{0}}\) . The positive equilibrium \((\frac{2}{3},\frac{4}{15})\) undergoes a Hopf bifurcation.Back to article page
