Add to ORKGAbstract. We give sufficient conditions that the homogeneous dif-ferential equations: for t t0(> 0), x′′(t) + q(t)x′(t) + p(t)x(t) = 0, x′′(t) + q(t)x′(t) + F (t, x(ϕ(t))) = 0 are oscillatory where 0 ϕ(t), 0 < ϕ′(t), lim t→∞ϕ(t) =1 and F (t, u) sgn u p(t)juj. We obtain comparison theorems. 1
