An Impulsive Three-Species Model with Square Root Functional Response and Mutual Interference of Predator

Figure 3

(a) is the existence of the positive periodic solution of system (4) with initial values of , which implies that system (4) is permanent; (b) is phase portrait of positive periodic solution of system (4); (c) is dynamic behavior of system (4) with the mutual interference of the predator ; other parameters are also the same as (a).
