Research Abstract |
From the viewpoint of pattern formations, we show the structure of stationary solutions depending on the parameter, for example, diffusion coefficients. The bifurcation theory is applicable to prove the existence of non constant solutions. To show the existence of a traveling solution corresponding to a propagating arc-like segment which is observed in the experiment of BZ reaction system with feedback, we study some kind of the limiting system to the reaction diffusion equation.
