We propose new criteria to ensure that all obtained solutions are oscillatory. The obtained results can be used to develop and provide theoretical support for and further develop the oscillation study for a class of second-order neutral differential equations.

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, wherez(t)=x(t)+p(t)x(τ(t)),p∈C1([t0,∞),[0,∞)), andα≥1. Our results improve and extend some known results in the literature. Some examples are also provided to show the importance of these results.
