摘要：In this paper, we consider the second-order Emden-Fowler neutral delay dynamic equation ( r ( t ) z Δ ( t ) α − 1 z Δ ( t ) ) Δ + q ( t ) x ( δ ( t ) ) β − 1 x ( δ ( t ) ) = 0 $$\bigl(r(t)\bigl\vert z^{\Delta}(t)\bigr\vert ^{\alpha-1}z^{\Delta}(t) \bigr)^{\Delta}+q(t)\bigl\vert x \bigl(\delta(t) \bigr)\bigr\vert ^{\beta-1}x \bigl(\delta(t) \bigr)=0 $$ on time scales, where z ( t ) = x ( t ) + p ( t ) x ( τ ( t ) ) $z(t)=x(t)+p(t)x (\tau(t) )$ and β ≥ α > 0 $\beta\geq\alpha>0$ are constants. By means of the Riccati transformation and inequality technique, some oscillation criteria are established, which extend and improve some known results in the literature.
