The analytic solution to the model without dispersion is found and is shown to display periodic exponential growth rather than asynchronous (or balanced) exponential growth. It is shown that a bounding envelope (hull) of the solution to the model without dispersion takes the same shape as the limiting steady size-distribution (SSD) to the dispersive case as dispersion tends to zero. The effect of variable growth rate on the shape of the hull is also discussed.enAll Rights ReservedDiscussion / Working PapersFields of Research::49 - Mathematical sciences::4901 - Applied mathematics::490102 - Biological mathematics
