We consider the periodic scalar neutral functional differential equation Ε½ .w Ε½ . Ε½ . Ε½ .x Ε½ Ε½ ..

The two time-
This paper deals with the existence of periodic solutions for some partial functional differential equations with infinite delay. We suppose that the linear part is nondensely defined and satisfies the HilleαYosida condition. In the nonlinear case we give several criteria to ensure the existence of

This extends the study of deriving periodic solutions from bo
In this paper we give necessary and sufficient conditions for the existence of periodic solutions for convex functional differential equations of neutral type with finite and infinite delay.
