Abstract

Systems far from equilibrium state exhibit in certain conditions complex behavior in the form of spatio-temporal structures. Such systems, which present a rich dynamic behavior, are becoming a growing field of research in the last decades. In particular, models for reaction-migration systems in the electrified solid/liquid interface have been considered ideal for investigations in both, theoretically and experimentally point of views. In this project we propose a theoretical study of edge effects obtained when we take into considerations integral coupling under different geometries. The theoretical approach basically consists in the development of analytical solutions based on Kernel functions. (AU)
