摘 要:
In this talk, I will report our recent works on Turing instability of the periodic solutions for general reaction-diffusion system with cross-diffusions and the patch model of n-coupled reactors with cross-diffusion like coupling. In a general setting, we establish a formulae in terms of the diffusion rates (not necessarily limited to either larger diffusivity or smaller diffusivity) to determine Turing instability of the Hopf bifurcating periodic solutions. Then, we supply an example of the reaction-diffusion Lengyel-Epstein model which is used to characterize the CIMA chemical reactions to demonstrate how our results can be applied.
