Abstract

A coupled two-cell Brusselator model with diffusion effect subject to Neumann boundary condition is considered. Hopf bifurcations and global steady state bifurcations which bifurcate from the unique positive constant equilibrium point are investigated in detail. Meanwhile, Turing instability occurs when diffusion is present. Particularly, we show the existence of spatially inhomogeneous periodic solutions and non-constant steady state solutions, which exhibit rich spatiotemporal patterns in this coupled Brusselator system. Some numerical simulations are presented to illustrate the theoretical results obtained.
