Traveling spots and traveling fingers in singular limit problems of reaction-diffusion systems
Traveling spots and traveling fingers in singular limit problems of reaction-diffusion systems
In this study, we consider the traveling spots that were observed in the photosensitive Belousov-Zhabotinsky reaction experiment conducted by Mihailuk et al. in 2001. First, we introduce the interface equation by the singular limit analysis of a FitzHugh--Nagumo-type reaction-diffusion system. Then, we obtain the profile of the support of the …
