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

Figure 2

Dispersion relations for different parameters: in (a), curves of the real part of the eigenvalue are derived by taking 𝑎₂₁=10, 𝑎₁₂=𝑎₂₂=0.01, and 𝑎₁₁=0.05,0.1,0.15,0.18,0.201,0.25 from top to bottom; in (b) 𝑎₂₁=10, 𝑎₁₁=𝑎₂₂=0.01, and 𝑎₁₂=0.15,0.2,0.25,0.3,0.353,0.4 from top to bottom; and in (c) 𝑎₂₁=5.06, 𝑎₁₁=𝑎₁₂=0.01, and 𝑎₂₂=0.35,0.4,0.45,0.508,0.558,0.608 from top to bottom. Other parameters are fixed as in (21).
