I have carried out research in this topic in collaboration with Dr. J. Güémez (from the Universidad de Cantabria). Our research started when we discovered a transition induced by noise between a chaotic attractor and a fixed-point attractor coexisting with it. Later we discovered other types of transitions too. Our work relied on a master-equation representation of the noisy dynamics in a finite-size chemical reaction.
The following papers contain our results in this field:
