Abstract: In this paper,we study the existence multiplicity and nonexistence of positive ω-periodic solutions for a kind of nonautonomous functional differential equation by employing the fixed point therem in cones.Some new results axe obtained.As an application of our sesults,we discuss the existence of a positive periodic solution for a class of models of blood cell production with a parameter,which has not been investigated by using previous methods.
