Fronts between Hopf- and Turing-type domains in a two-component reaction-diffusion system

Abstract

Propagating and standing fronts between Hopf- and Turing-type domains are observed experimentally on a one-dimensional array of resistively coupled nonlinear LC-oscillators describable by a two-component reaction-diffusion equation. Numerical and experimental results are compared in particular with respect to front velocities. In the neighbourhood of a codimension-two point two coupled Ginzburg-Landau equations, derived by multiple scale methods, are useful approximation.
