Fig. 14

Plot of the solutions to equation (37) for $A=10$, $E=1.2$, $I=0.7$. The curves shown are $t=2/\beta$ (red), $t=1/\beta$ (blue), $t=\overline{t}(\beta )$ (dashed black), and $t=\underline{t}(\beta )$ (large dotted black). Note that $\underline{t}(\beta )<1/\beta$ and that $\overline{t}(\beta )$ rises up from $t=1/\beta$ to its maximum at $t=2/\beta$ and then decays, in agreement with Proposition 5.
