Résumé :

This paper is concerned with population systems whose evolution is described by differential equations with not necessarily extensive transition rates. Some standard models in marketing, epidemiology and ecology are used to show how such systems can actually occur in concrete situations. The implications of the extensivity or not of the interaction rates are discussed and interpreted, with special emphasis on the qualitatively different behaviors induced. © 1988.
