Abstract

We prove that the stationary solution of a class of reaction-diffusion systems is stable in the intersection of the Sobolev space H1(ℝ) and an exponentially weighted space Hα1(ℝ). Particular attention is given to a special case, the combustion model. The stationary solution considered here is the end state of the traveling front associated with the system, and thus the present result complements recent work by A. Ghazaryan, Y. Latushkin and S. Schecter, where the stability of the traveling fronts was investigated.
