. We study a singular perturbation problem for a certain type of reaction diffu- sion equation with a space-dependent reaction term. We compare the effect that the presence of boundary layers versus internal layers has on the existence and stability of stationary solutions. In particular, we show that the associated eigenvalues are of different orders of magnitude for the two kinds of layers. other boundary layers in very similar. We first study the case on φ 1 and take care of any possible Dirichlet boundary condition afterward.
