Global stability of traveling waves for nonlocal time-delayed degenerate diffusion equation

Abstract

This paper is concerned with a class of nonlocal reaction-diffusion equations with time-delay and degenerate diffusion. Affected by the degeneracy of diffusion, it is proved that, the Cauchy problem of the equation possesses the Hölder-continuous solution. Furthermore, the non-critical traveling waves are proved to be globally L1-stable, which is the first frame work on L1-wavefront-stability for the degenerate diffusion equations. The time-exponential convergence rate is also derived. The adopted approach for the proof is the technical L1-weighted energy estimates combining the compactness analysis, but with some new development.
