Abstract:

For scalar reaction-diffusion equations in one space dimension, it is known for a long time that fronts move with an exponentially small speed for potentials with several distinct minimizers. The purpose of this paper is to provide a similar result in the case of systems. Our method relies on a careful study of the evolution of the localized energy. This approach has the advantage to relax the preparedness assumptions on the initial datum.

Keywords: reaction-diffusion systems, interfaces, fronts, slow motion
