Figure 3From: Stability and bifurcation in a single species logistic model with additive Allee effect and feedback controlThe phase portraits of system (1.6) when \(m=a\): (a) Two equilibria \(E_{0}\) and \(E_{2}\). \(E_{0}\) is a saddle-node and \(E_{2}\) is a stable node. (b), (c) A trivial equilibrium \(E_{0}\) which is a saddle-nodeBack to article page
