Part of the Lecture Notes in Biomathematics book series (LNBM, volume 20)


Many, if not most differential models which are used in an attempt to describe the dynamics of a population of a single species or several interacting species are formulated by prescribing in some appropriate manner the instantaneous per unit growth rate of each species:
$$ {N'_{1}}/{N_{i}} = {f_{i}},\quad i = 1,\; \ldots ,\;n,\quad n \geqslant 1$$
