using the theory of coincidence degree, the existence of positive periodic solutions for a delayed model in population is proved. A new result is obtained. Some related results are improved.

In this paper, we employ some new techniques to study the existence of positive periodic solutions of the neutral delay model Our result gives a correct answer to the open problem 9.2 due to Y. Kuang
In this paper, criteria on uniform ultimate boundedness are derived for impulsive delay di erential equations using Lyapunov functions and Razumikhin techniques. It should be noted that the boundedness criteria establish global existence of solutions as well as boundedness without assuming, a priori
It is pointed out that the asymptotic general solution to the 0-model equation for a periodic carrying capacity K(t) and t ~, r-~ is identical in form to the generalized logistic equation solution with a built-in developmental time delay z(~ r-~) and associated parameter ranges of primary biological
