摘要
This paper is concerned with the asymptotic stability of traveling wave fronts of a class of nonlocal reaction-diffusion equations with delay. Under monostable assumption, we prove that the traveling wave front is exponentially stable by means of the (technical) weighted energy method, when the initial perturbation around the wave is suitable small in a weighted norm. The exponential convergent rate is also obtained. Finally, we apply our results to some population models and obtain some new results, which recover, complement and/or improve a number of existing ones. (C) 2009 Elsevier Inc. All rights reserved.
