Figure 3. Wave instability phase diagram in the Inline graphicInline graphic plane.

Figure 3

Regions marked in pink denote the unstable waves. (a) the diffusion(−)–diffusion(+) model, when Inline graphic. (b) the adsorption(−)–diffusion(+) model. (c) the diffusion(−)–adsorption(+) model. (d) the adsorption(−)–adsorption(+) model when Inline graphic. In (a) and (c) the dashed line marks the values along which the bifurcation graph (Fig. 5) was plotted. In (b) and (c) the threshold value of Inline graphic is denoted by Inline graphic.
