In this paper sufficient conditions are obtained so that every bounded solution of
(y(t)-p(t)y(t-τ))' + Q(t)G(y(t-σ)) = f(t)
oscillates or tends to zero as t→1, where the coefficient functions Q(t), and f(t) are assumed to be oscillatory. It is known that such assumptions on coefficient functions are very rare in literature. Different ranges for p(t) are considered including the case when p(t) changes sign. The results hold for all types of the non-linear function G and also hold when f(t)≡0.
