Spatiotemporal Pattern in a Self- and Cross-Diffusive Predation Model with the Allee Effect

Figure 3

Variation of dispersion relation of model (5) for different 𝐷₁₂: (A) 𝐷₁₂=−1.6<𝐷^T₁₂, the Turing instability occurs; (B) 𝐷₁₂=𝐷^T₁₂=−0.31, the critical Turing value; and (C) 𝐷₁₂=0.4>𝐷^T₁₂, the Turing instability decays. Other parameters values are fixed as (27) in the text.
