Abstract
A strong analogy is found between the evolution of localized disturban ces in extended chaotic systems and the propagation of Fronts separati ng different phases. A condition for the evolution to be controlled by nonlinear mechanisms is derived on the basis of this relationship. An approximate expression for the nonlinear velocity is also determined by extending the concept of the Lyapunov exponent to a growth rate of finite perturbations.
