摘要
运用Riccati变换技术和不等式技巧,研究了一类二阶非线性中立型时滞微分方程的振动性,给出了此类方程所有解区间振动的两个充分条件,推广并改进了已有的结果.
By generalized Riccati transformation and inequality technique, an oscillation of secondorder nonlinear neutral delay differential equation is studied, and two sufficient conditions are obtained for interval oscillation for this equation. The results in this paper extend and improve the results given in literatures.
