Oscillation Results for Second-Order Quasi-Linear NeutralDelay Differential Equations

In this paper, some new oscillation criteria are obtained for the secondorder quasi-linear neutral delay differential equationrinsert ignore into journalissuearticles values(t);| xinsert ignore into journalissuearticles values(t); + pinsert ignore into journalissuearticles values(t);xinsert ignore into journalissuearticles values(τ insert ignore into journalissuearticles values(t);); |α−1xinsert ignore into journalissuearticles values(t); + pinsert ignore into journalissuearticles values(t);xinsert ignore into journalissuearticles values(τ insert ignore into journalissuearticles values(t););+ f t, xinsert ignore into journalissuearticles values(σinsert ignore into journalissuearticles values(t);); = 0, t ≥ tunder the case when∞ t r α insert ignore into journalissuearticles values(t); ment some known results in the literature.
