摘要:A depletion-type reaction-diffusion Gierer-Meinhardt model with Langmuir-Hinshelwood reaction scheme is introduced. Boundedness of positive solution of the parabolic system and constant steady state solutions of the model are exhibited. Stability of the corresponding positive constant steady state is explored.Some priori estimates, the properties of nonconstant steady states, non-existence and existence of the nonconstant steady state solution for the corresponding elliptic system are investigated by Leray-Schauder degree theory, respectively. Some existence conditions and some properties of the Hopf bifurcation and the steady state bifurcation are presented, respectively. It is showed that the temporal and spatial bifurcation structures will appear in the reaction-diffusion model.
