A geometric construction of travelling wave solutions to the Keller--Segel model

Kristen Harley, Peter van Heijster, Graeme John Pettet


We study a version of the Keller--Segel model for bacterial chemotaxis for which explicit travelling wave solutions are known in the zero attractant-diffusion limit. Travelling wave solutions are constructed in the small diffusion case using geometric singular perturbation theory, which converge to the explicit solutions in the singular limit.
