Dynamical trajectories using γ near${\gamma }_1^c$Dynamical trajectories of the system (1) considering the values of parameters given in Table 2, except γ near ${\gamma }_1^c$. When T(0) = 0.45 (for T(0) = 0.44 both cases go to ${\bar{Q}}^0$), ${\bar{Q}}_{>}^{*}$ is the attracting point for γ = 2.31 × 10^-2 (a), and limit cycle with small amplitude circulating unstable ${\bar{Q}}_{>}^{*}$ appears for γ = 2.32 × 10^-2 (b). The scales of vertical and horizontal axes must be multiplied by the factors shown in the legends to obtain the actual values.
