Spatial resonances and superposition patterns in a reaction-diffusion model with interacting turing modes

Spatial resonances leading to superlattice hexagonal patterns, known as black-eyes, and superposition patterns combining stripes and/or spots are studied in a reaction-diffusion model of two interacting Turing modes with different wavelengths. A three-phase oscillatory interlacing hexagonal lattice pattern is also found, and its appearance is attributed to resonance between a Turing mode and its subharmonic.
