Trajectories of system (1) with different parameters and initializations in regions (IIIV and X) of Fig. 1. For convenience, parameter values are given directly at the label of the graph. (a)Two unstable periodic solutions coexist with the initial value \((0.2932,1.5887)\) and \((0.3601,4.038)\), respectively, one of which is stable to the origin. (b)An unstable periodic solution with the initial value \((0.2233,2.1588)\) and an asymptotically stable solution with the initial value \((0.1265,1.2177)\). (c) and (d) have opposite phenomena, one which is asymptotically stable with the initial value \((0.3034,5.555)\), and the other is unstable with the initial value \((0.4632,5.5445)\)
