Environmental periodicity and time delays in a “food-limited” population model
Abstract Sufficient conditions are obtained for the existence of a globally attracting positive periodic solution of the “food-limited” population system modelled by the equation N (t) = r(t)((K(t) − N(t − mω)) (K(t) + c(t)r(t) N(t − mω))) , where m is a nonnegative integer and K, r, c are continuous positive periodic functions of period ω.
