Qualitative Analysis of a Leslie-Gower Predator-Prey System with Nonlinear Harvesting in Predator

Figure 1

This diagram shows the number and location of the positive interior equilibrium points of system (5). The green, red, and black color curves are the predator nullclines for different values of and the straight line is the prey nullcline: (a) , for black color parabola , for red color parabola , and for green color parabola ; (b) ; (c) .
