Figure 4From: Dynamic analysis of a prey–predator model with state-dependent control strategy and square root response functionThe schematic of the existence of the order-1 periodic solution in Case II. (a) Discussion in subcase \(x_{P_{2}}\geq(1-a)h\). (b) Discussion in subcase \(y_{P_{1}^{+}}> y_{F_{1}}\) or \(y_{P_{1}^{+}}< y_{F_{2}}\). (c) Discussion in subcase \(y_{F_{1}}< y_{P_{1}^{+}}< y_{F_{2}}\)Back to article page
