abstract = {<p style="text-align: justify;">In this paper, we study the spatiotemporal patterns of a Brusselator model with discrete time-space by using the coupled mapping lattice
(CML) model. The existence and stability conditions of the equilibrium point
are obtained by using linear stability analysis. Then, applying the center
manifold reduction theorem and the bifurcation theory, the parametric conditions of the flip and the Neimark-Sacker bifurcation are described respectively.
Under space diffusion, the model admits the Turing instability at stable homogeneous solutions under some certain conditions. Two nonlinear mechanisms,
including flip-Turing instability and Neimark-Sacker-Turing instability, are presented. Through numerical simulation, periodic windows, invariant circles,
chaotic phenomenon and some interesting spatial patterns are found.</p>},
