The aim of this study is to compare the growth speed of different cell populations measured by their Malthus parameter. We focus on both the age-structured and size-structured equations. A first population (of reference) is composed of cells all aging or growing at the same rate v̄. A second population (with variability) is composed of cells each aging or growing at a rate v drawn according to a...
