Abstract
Time-dependent structures in convection such as traveling patterns are examples of nonlinear waves and represent space-time ordered structures. They can be described by an amplitude equation (the complex Landau-Ginzburg-Newell model). Defects occur as the result of localized modulations of the phase and play a major role in the mechanisms of progressive disorganization of the coherent structures. Most of our experimental findings concerning the nucleation and the stability of the defects are numerically simulated by the appropriate Landau-Ginzburg-Newell model.
