Abstract:
New oscillation criteria are established for the second‐order nonlinear neutral functional differential equations of the form (r(t)|z′(t)|α−1z′(t))’+f(t,x[σ(t)])=0, t ≥ t0, where z(t) = x(t) + p(t)x(τ(t)), p ∈ C1([t0, ∞), [0, ∞)), and α ≥ 1. Our results improve and extend some known results in the literature. Some examples are also provided to show the importance of these results.
