Oscillation Criteria for Neutral Differential Equations of Higher Order

给出了关于n阶中立型微分方程(x(t)±p(t)x[τ(t)])(n)+q(t)x[σ(t)]=0的一些新的振动性准则,所得结果推广并改进了Budincevic,ChuanxiQ和LadasG,GopalsamyK,LalliBS和ZhangBG给出的一些结论.

The author presents some new oscillatory criteria for the n-th order neutral differential equations of the form (x(t)±p(t)x[τ(t)])~ (n)+q(t)x[σ(t)]=0. The results obtained extend and improve some known criteria that were given by Budincevic, Chuanxi Q and Ladas G, Gopalsamy K, Lalli B S and Zhang B G.
