Abstract: | In this paper, necessary and sufficient conditions for the oscillation and asymptotic behaviour of solutions of the second
order neutral delay differential equation (NDDE) are obtained, where q, h ∈ C(0, ∞), ℝ) such that q(t) ≥ 0, r ∈ C
(1) (0, ∞), (0, ∞)), p ∈ C (0, ∞), ℝ), G ∈ C (ℝ, ℝ) and τ ∈ ℝ+. Since the results of this paper hold when r(t) ≡ 1 and G(u) ≡ u, therefore it extends, generalizes and improves some known results.
