Titre : Monotone abstract non densely defined Cauchy problems applied to age structured population dynamics models

Résumé : In this presentation we first derive some sufficient conditions to establish the monotonicity and comparison principles of the semi-flow generated by non-densely defined Cauchy problems. We apply our results to a class of age structured population models. As a consequence we obtain a monotone semiflow theory and some comparison principles for age structured models.
