摘要
运用广义Riccati变换技术,研究时标上二阶扰动非线性中立型动力方程振动的充分条件,所得结论推广和改进了已知文献的部分结果,最后给出了具体例子.
A new sufficient condition on the oscillation of the second order perturbed nonlinear neutral dynamic equations is given by being generalized Riccati transformation.Some results in the literature are improved and generalized.Finally,a specific example that dwells upon the sharp conditions of our result is given.
