| Research Abstract |
In reaction-diffusion systems, when diffusion coefficients are very small, solutions sometimes form transition layers. In this research, we consider a model in population genetics which is described by a reaction diffusion equation. We will rigorously prove, under certain conditions, that this equation has a unique nontrivial steady-state, it is linearly stable and has transition layers.
