Simple epidemics Solve directly equations Solution over time Phase-portrait (picture) Tmes implct Equilibria (ODEs = 0) Stability of equilibria This simple diagram tells you roughly how the system behaves. It’s called the phase line. The phase line captures exactly the information we use to get the qualitative sketch of solution curves. We illustrate this with some examples. 2.

Two models of nonlinear chemical oscillators, the cross-shaped phase diagram model of Boissonade and De Kepper and the Oregonator, are modified by deleting a feedback species and mimicking its effect by a delay in the kinetics of another variable. Write this equation as a first order nonlinear system $x' = y , \qquad y' = -x+x^2 .$ The phase portrait with some trajectories is drawn in Figure 8.1. Figure 8.1: Phase portrait with some trajectories of $$x'=y, y'=-x+x^2$$. From the phase portrait it should be clear that even this simple system has fairly complicated behavior.
