Travelling wave solutions in a negative nonlinear diffusion-reaction model

Analysis of PDEs 2020-09-17 v2

Abstract

We use a geometric approach to prove the existence of smooth travelling wave solutions of a nonlinear diffusion-reaction equation with logistic kinetics and a convex nonlinear diffusivity function which changes sign twice in our domain of interest. We determine the minimum wave speed, c*, and investigate its relation to the spectral stability of the travelling wave solutions.
