Assess students' ability to analyze linear stability and bifurcation structure of reaction–diffusion systems with cross‑diffusion and nonlinear kinetics. Expect derivation of dispersion relations and Turing instability conditions including cross‑diffusion terms, weakly nonlinear amplitude equations to classify super/subcritical bifurcations, use of numerical continuation to track solution branches and identify codimension‑two points, and interpretation of pattern selection as parameters vary.
