Logistic growth described by birth-death and diffusion processes
A Di Crescenzo, P Paraggio - Mathematics, 2019 - mdpi.com
We consider the logistic growth model and analyze its relevant properties, such as the limits,
the monotony, the concavity, the inflection point, the maximum specific growth rate, the lag …
