title: Dynamics of populations with age-difference and diffusion: localization.
abstract: "In this paper we study the behavior of the solutions of the Gurtin-MacCamy model for the dynamics of populations with [spatial] diffusion and age-dependence.  We give sufficient conditions on the birth and death modules for the population to remain localized in a fixed interval or to ultimately cover all the domain."
