Modern, high-performance methods like the Conjugate Gradient (CG) method, GMRES (Generalized Minimal Residual), and BiCG .
We analyze pattern formation and long-time behavior in a class of nonlinear reaction–diffusion equations on bounded domains. Using linear stability analysis, weakly nonlinear expansions, and numerical simulations, we identify parameter regimes producing Turing patterns, characterize bifurcations, and compare analytic predictions with computed steady states and transient dynamics. math 6644
