Monotonicity and uniqueness of traveling waves in bistable systems with delay

Yun-Rui Yang, Nai-Wei Liu

Abstract:
This article establishes the monotonicity, uniqueness and Liapunov stability of traveling waves for bistable systems with delay. We use an elementary super-subsolution comparison method and a moving plane technique. Also an example is given to illustrate our results.
