Pattern Formation in a Bacterial Colony Model

Figure 2

The dispersal relation of 𝛾 with 𝛽. Parameters: 𝛼=1.8, 𝐷_𝑢=0.02, 𝜎=18. The blue and red curves represent Hopf and Turing bifurcation curves, respectively. They separate the parametric space into three domains, and domain(III) is called Turing space.
