Abstract
The effect of external fields on non-equilibrium structures is discussed in the framework of amplitude equations of the Ginzburg-Landau type. This approach is well adapted to the study of pattern formation in liquid crystals which, on the other hand, provide a class of easily forced systems. A few examples, related to experimental observations, are presented. In particular, in the case of spatio-temporal Hopf bifurcations, it is shown how pure temporal or spatial modulations may stabilize standing waves or two-dimensional wave patterns in regimes where they are otherwise unstable.
