Patterns and waves are basic and important phenomena that govern the dynamics of physical and biological systems. This can be seen, for instance, in morphological phases in diblock copolymers, skin pigmentation in cell development and semiconductor gas-discharge systems. The FitzHugh-Nagumo model, which was originally derived as an excitable system for studying nerve impulse propagation, is now of great interest to the scientific community as breeding ground for patterns, traveling waves, and other localized structures. This talk is aimed at recent results obtained by variational methods.
