Figure 6From: 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 \(\pmb{\tau_{1} = 2.8 > \tau_{1_{0}}}\) , \(\pmb{\tau_{2} = 3.0}\) . Hopf bifurcation occurs from the positive equilibrium \(E^{ *} (x^{ *},y^{ *} ) = (\frac{2}{3},\frac{11}{30})\).Back to article page
