Abstract

We provide an asymptotic analysis of a fractional Fisher-KPP type equation in periodic non-connected 1-dimensional media with Dirichlet conditions outside the domain. After demonstrating the existence and uniqueness of a non-trivial bounded stationary state n_+n\_+ , we prove that the stable state n_+n\_+ invades the unstable state 0 with a speed which is exponential in time.
