Wang, Shousong; Yan, Gang Dynamics of the effect of constant toxicant on the populations stimulated by generalized logistic model. (Chinese. English summary) Zbl 0966.92029 Acta Sci. Nat. Univ. Sunyatseni 38, No. 5, 4-8 (1999). Summary: The dynamics of a generalized logistic model polluted by a constant toxicant in time is studied in detail. By analyzing the asymptotic properties of the solution, we obtain the pollution conditions that will lead to different results (peristence or extinction) of the populations.
