The schnakenberg model with precursors
WebbAbstract. 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 ... Webb9 nov. 2024 · Schnakenberg model is known as one of the influential model used in several biological processes. The proposed model is an autocatalytic reaction in nature that …

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.
