Abstract

We investigate the selection of structures generated by diffusive instabilities in asymmetric bistable systems. It is shown that the nonlinear coupling between the zero mode and the different spatial modes emanating from the two homogeneous states can give rise to self-parametric instabilities favoring the occurrence of stable resonant rhombic and superlattice patterns.
