Traveling waves of a diffusive modified Leslie-Gower model with chemotaxis

Shuna Wang, Jiang Liu, Jun Fang, Xiaojie Lin

Abstract:
In this article, we study a diffusive modified Leslie-Gower model with chemotaxis and large wave speed. By applying traveling wave transformation and changing the time scale, this modified Leslie-Gower model can be transformed into a singularly perturbed system. We establish the existence of heteroclinic orbits connecting different equilibria for the system without perturbation by constructing invariant regions and using the Poincare-Bendixson theorem. Then the existence of traveling wave solutions for the diffusive modified Leslie-Gower system is demonstrated via the geometric singular perturbation theory and Fredholm theory.
