Figure 5.
Emergent global landscape φ(u) for the reaction kinetic system (3.1), given by (3.7) with α = 0.1 and several values of γ: From left to right: lnγ = 2.044, 3.00, 3.014, 3.045, 3.258. The macroscopic phase transition occurs at γ* = 20.36, when the two local minima have an equal height [38]. The minima (maxima) correspond to the stable (unstable) steady states in figure 4.
