Abstract:

An autocatalytic reversible three-molecular biochemical reaction model subject to Neumann boundary conditions is considered. Firstly, the existence and stability of the Hopf bifurcation for the ordinary differential system are given. Secondly, the effect of diffusion coefficients on Turing instability is established and the existence of Hopf bifurcation is obtained for the partial differential system with diffusion. Then applying the normal form theory and center manifold theorem, the direction and stability of Hopf bifurcation are also given. Finally, some numerical simulations are carried out with the help of Matlab software to verify and supplement the theoretical results.

Key words: Reversible biochemical reaction, Turing instability, Hopf bifurcation, Stability
