摘要：In this talk, I will report our recent works on Turing instability of both the periodic solutions and steady states for both one reactor-based reaction-diffusion systems and the membrane-coupled reaction systems. For the one reactor-based reaction-diffusion systems, we emphasize on Turing instability of the spatially homogeneous periodic solutions, while for the membrane coupled reaction-diffusion systems, we are interested in studying Turing instability of both the spatially non-homogenous and non-constant steady states. The methods are based on the singular limit eigenvalue problem and the regular perturbation methods.
