摘要: In this paper, we are concerned with a reaction-diffusion model, known as the Sel'kov-Schnakenberg system, and study associated steady state problem. We obtain existence nonexistence results of nonconstant states, which in turn imply criteria for formation spatial pattern (especially, Turing pattern). Our reveal different roles diffusion rates two reactants generating pattern.
