Travelling waves for the population genetics model with delay

Abstract

Under the assumptions that the spatial variable is one-dimensional and the distributed delay kernel is the general Gamma distributed delay kernel, when the average delay is small, the existence of travelling wave solutions for the population genetics model with distributed delay is obtained by using the linear chain trick and geometric singular perturbation theory. On the other hand, for the population genetics model with small discrete delay, the existence of travelling wave solutions is obtained by employing a technique which is based on a result of the existence of inertial manifold for small discrete delay equations.
