摘要

借助时间尺度的有关理论,运用Riccati变换技巧,给出时间尺度上二阶非线性中立型时滞动力方程的新的振动准则.推广并改进时标上二阶非线性时滞动力方程振动性的一些结果.%By means of the theory of time scales and Riccati transformation technique, we establish some new oscillation criteria for the second-order nonlinear neutral delay dynamic equations on time scales. Our result generalizes and improves some known results for the oscillation of second-order nonlinear delay dynamic equations on time scales.
