摘要
利用广义Riccati代换给出了时标上一类三阶中立型动力方程的振动准则,其结果不仅得到了几个振动解存在的条件,也拓展了一些已有的结论,在最后还给出了几个例子来验证结论.
It is the purpose of this paper to give oscillation criteria for third order nonlinearneutral delay dynamic equations.Our results are not only new for third order nonlinear delay dynamic equations but also extend many known results for oscillation of third order equations.And some examples are given.
