title: Urbanization in some hierarchical urban models.
abstract: "This paper examines two aspects of hierarchical urban models:  the variations of total urban population and that of the urbanization ratio, in function of the number of hierarchical levels.  Both variations are analysed through four categories of models.  The complexity of the results suggests two approximations in order to make the analysis more tractable."
