Periodic solution of a periodic neutral delay equation

[摘要] Sufficient conditions are obtained for the existence of a positive periodic solution of the periodic neutral delay equation (N) over dot (t) = N(t)[a(t) - Sigma(j = 1)(n)b(j)(t) N(t - sigma(j)) - Sigma(j = 1)(n)c(j)(t)(N) over dot (t - tau(j))], which arise in a ''food-limited'' population model.
