The higher order neutral functional differential equation $\frac{d^{n}}{d t^{n}} [x (t) + h (t) x (τ (t))] + σ f (t, x (g (t))) = 0 (1)$ is considered under the following conditions: $n \geq 2$ , $σ = \pm 1$ , $τ (t)$ is strictly increasing in $t \in [t_{0}, \infty)$ , $τ (t) < t$ for $t \geq t_{0}$ , ${lim}_{t \to \infty} τ (t) = \infty$ , ${lim}_{t \to \infty} g (t) = \infty$ , and $f (t, u)$ is nonnegative on $[t_{0}, \infty) \times (0, \infty)$ and nondecreasing in $u \in (0, \infty)$ . A necessary and sufficient condition is derived for the existence of certain positive solutions of (1).

In this paper we study the existence of classical solutions for a class of abstract neutral integro-differential equation with unbounded delay. A concrete application to partial neutral integro-differential equations is considered.
