Abstract:Consider the discrete delay logistic model

$$N_{n + 1}  = \frac{{aN_n }}{{1 + \beta N_{n - k} }},        n = 0,1,2,...$$
(1)
where α∈(1,∞), β(0,∞), andk∈{0,1,2,...}. We obtain new sufficient conditions for the positive equilibrium (α−1)/β of (1) to be a global attractor. This work is partially supported by the Foundation for Excellent Youth Teachers of State Educational Commission.
Keywords:Logistic model  delay  discrete  global attractivity
