In this research we introduce and study, analytic and numerically, a model of chemostat with distributed delay. This a generalization of the model, with no delay, first treated by Kuang. We give conditions for asymptotic stability, survival of species or extinction of them. This research has been partially supported by Central Bank of Venezuela. 2050 Mario(More)
In this paper we study the following system of differential equations with time lag: S′(t) = γS(t)(1− S(t) K )− mX(t)S(t) a + S(t) X ′(t) = mX(t)S(t− τ) a + S(t− τ) −DX(t), Recibido 2000/04/28.
