Dynamical trajectories using β
= 10.0. Dynamical trajectories of the system (1) considering the values of parameters given in Table 2, except β1 = 10.0. The initial conditions determine the region of attraction: trivial for T(0) = 0.151 (a), or non-trivial for T(0) = 0.152 (b). The scales of vertical and horizontal axes must be multiplied by the factors shown in the legends to obtain the actual values.
