Abstract: Some new criteria are given for the oscillation of solutions of perturbed functional-differential equations of the form

$\displaystyle ({\text{I}})\quad {x^{(n)}} + P(t)f(x(g(t))) = Q(t).$

The results are new even in the case $ g(t) \equiv t$, or when $ ({\text{I}})$ is linear. The function $ Q(t)$ does not have to be small or periodic.
