Fig 4. Influcence of noise on the maxima of the stationary solution.

Influence of noise on the maxima of the stationary solution, showing that noise shifts the maxima to the extent that bifurcations can be destroyed or induced. The red line shows the deterministic fixed points, the first black line shows the solution for a burst size 1 (the standard Schlögl model). With each further black line, the burst size r increases by 10. Starting from the first black curve next to the red one, the parameter value r of the black curves are therefore: 1,11,21,31,41. The other parameters are (a) ${\tilde{k}}_2=1.65·{10}^5,{\tilde{k}}_3=720$, (b) ${\tilde{k}}_1=5.33·{10}^6,{\tilde{k}}_3=800$, (c) ${\tilde{k}}_1=8·{10}^6,{\tilde{k}}_2=1·{10}^5$.
