Turing Patterns in a Predator-Prey System with Self-Diffusion

Figure 3

Snapshots of contour pictures of time evolution of 𝑢₁ and 𝑢₂. From top to bottom: patterns of 𝑢₁,𝑢₂ for 𝑎₁₁=0.05 and of 𝑢₁,𝑢₂ for 𝑎₁₁=0.1. From left to right: 2×10³ iterations, 4×10⁴ iterations, and 1×10⁶ iterations. Other diffusion parameters: 𝑎₁₂=𝑎₂₂=0.01 and 𝑎₂₁=10.
