摘要
研究了一类具振动系数的偶数阶非线性中立型微分方程,通过利用广义Riccati变换和引入参数函数,得到了该类方程振动的若干充分条件,所得结果推广了已有的相应结论。
A class of even order nonlinear neutral differential equations with oscillating coefficients is studied, some sufficient conditions for the oscilliation of the equation are obtained by using the generalized Riccati transformation and introducing parameter function,the conclusions which we draw generalized the part conclusions.
