Sufficient conditions of oscillation for certain second-order functional dynamic equations on time scales(时间模上一类二阶泛函动态方程振荡的充分条件)
研究了一类时间模上二阶Emden-Fowler 型变时滞的中立型泛函动态方程{ a (t) φ([ x (t)+ p (t) g (x (τ (t))) ]Δ) }Δ + q1 (t) f1 (φ1 (x (δ1 (t))))+ q2 (t) f2 (φ2 (x (δ2 (t))))= 0 的振荡性,其中,φ(u)= |u|α - 1u(α> 0),φ1 (u)= |u|β - 1u(β>0),φ2 (u)= |u|γ - 1u(γ>0)。利用时间模上的有关理论和广义黎卡提变换技术,并借助各种不等式,得到了该方程振荡的一些新的充分条件,推广并丰富了一些已有结果。最后,给出了一...
