WebbSpot Patterns in the 2-D Schnakenberg Model with Localized Heterogeneities 3 to 80000. For time-stepping we used either a Backward-Euler time stepping scheme or a BDF-2 (backward di erentiation formula), the latter of which is preferable for computing spot amplitude temporal oscillations due to a Hopf bifurcation. Webb5 juni 2024 · The Schnakenberg model is a reaction-diffusion system which describe an autocatalytic chemical reaction [7]. In particular, this model is well-known as a model in pattern formation. Thus u(x,t)and v(x,t)represent the density of two chemical substances at t≥0and x∈(−1,1)and ε2>0and D>0are diffusion coefficients of uand v, respectively.

We develop novel mathematical techniques to study spot patterns in reaction-diffusion systems with space-dependent feed rate. The techniques are illustrated on the Schnakenberg model, which is a prototypical model of spot formation. Previous works have mostly addressed spot formation assuming the feed rate A is a constant, in which ...
