Turing Instability in the Standard Brusselator Reaction-Diffusion System

3 Turing Instability in the Standard Brusselator Reaction-Diffusion System [Pg.296]

We use the Brusselator, see Sect. 1.4.4, to illustrate these results. The steady state of the well-mixed system is stable ifb = 1 + see (1.83). Condition (10.35) implies that [Pg.296]

The second inequality is satisfied if the uniform steady state (PuU)- P (x)) = (a, h/a) is stable against uniform perturbation, that isb b. The Turing condition (10.40) reads [Pg.296]

If we consider b to be the control parameter, then the threshold for the Turing instability is given by [Pg.296]

In order for the Turing bifureation to occur first, the Turing threshold must lie below the Hopf threshold of the well-mixed system, b - bn- [Pg.296]
