The asymptotic stability of diverging traveling waves for reaction–advection–diffusion equations in cylinders

Abstract

This paper is devoted to the asymptotic stability of diverging traveling waves for reaction–advection–diffusion equation \(u_{t}-\Delta u+\alpha (t,y)u_{x}=f(t,y,u)\) in cylinders. By the sliding method, we first establish a Liouville-type result. Then, using the Liouville-type result and truncation technique, we prove the asymptotic stability of the diverging traveling wave.
