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.
