In this paper, a new mathematical model of bacterial culture in a chemostat is studied and analyzed. We study a general nonlinear age dependent population dynamics model which is a generalization of the chemostat model and obtain the existence, uniqueness, the semigroup property and the continuous dependence of the solutions on the initial data for the general model. Then, we show that the chemostat model is a particular case of the general model and hence conclude the wellposedness of the chemostat model.

Abstract

We study a general nonlinear age dependent population dynamics model which is a generalization of the chemostat model and obtain the existence, uniqueness, the semigroup property and the continuous dependence of the solutions on the initial data for the general model. Then, we show that the chemostat model is a particular case of the general model and hence conclude the wellposedness of the chemostat model.
