Wave Propagation and Wave Pattern Formation in Nonuniform Reaction-Diffusion Systems

摘要: The study of wave propagation and pattern formation in two- three- dimensional reaction-diffusion systems (RDS) has progressed significantly during the past 25 years since introduction homogeneous, isothermal, excitable chemical media [1–6]. While most basic properties waves have been studied spatially uniform systems, nonuniform ones is also considerable interest, because natural such as biological tissues ecological are strongly nonuniform. In only symmetry-breaking initial conditions give rise to new patterns [7]; nonuniformities gradients concentrations other local parameters bring with them an asymmetry, which generates routes for permits emergence types patterns.
