Papers on the Brusselator – early and recent

Model G is based on the Brusselator adding an extra G component. To understand Model G better we need to look at the Brusselator and how it was derived. See these papers below. N.B. sorry I can’t upload them to this site at the moment. Working on it. Brendan
