Interfacial instabilities and pattern formation have stimulated a great deal of studies during the last decenniums. In most cases, the interface is a moving boundary between two different states. Numerous examples of interface destabilization and interfacial patterns could be enumerated. For instances the zig-zag instability, undergone by straight rolls in two-dimensional extended systems like Rayleigh Bénard convection or electro-convection fluid systems, in gas discharge system, crystal growth, rifts in spreading wax layer and chevrons layer structure of smectic liquid crystals.

This current project proposes to study theoretically the mechanisms and characterize the complex dynamical behaviors exhibits by the interface that links a patterns state with an uniformed one.
