Figure 7From: Bogdanov–Takens bifurcation of a Holling IV prey–predator model with constant-effort harvestingWhen \((\mu _{1},\mu _{2})=(-0.01,-0.008)\) lies in region V, there are three equilibria \(E_{1}^{*}, E_{2}^{*}\) and \(E_{3}^{*}\). \(E_{1}^{*}\) and \(E_{3}^{*}\) are stable foci and \(E_{2}^{*}\) is a hyperbolic saddleBack to article page
