Abstract

A survey of three types of cell population models is presented in this paper. The main issue in all the surveyed words is whether or not there exists astable type distribution (s.t.d.). In the last few years, many efforts were directed towards describing the most general models which still exhibits.t.d. Progress made in the case ofsize density models are discussed. A slightly extended version of atime continous daughter cell model, studied in Arino et al. (1991), is presented. Recently, some authors have undertaken the task of comparing models of various origins and types. Such works are alluded to in a discussion
