ABSTRACT
We consider a reaction–diffusion equation in a domain consisting of two bulk regions connected via small channels periodically distributed within a thin layer. The height and the thickness of the channels are of order ε, and the equation inside the layer depends on the parameter ε and an additional parameter , which describes the size of the diffusion in the layer. We derive effective models for the limit , when the channel-domain is replaced by an interface between the two bulk-domains.
