摘要
对一种非线性中立型变时滞微分方程零点距进行了估计,利用微分方程与相应微分不等式之间的关系对非线性中立型变时滞微分方程振动解的零点分布进行了研究,进而推广和改进了已有的一些研究结果。
A Estimate is established for the distance between adjacent zeros of the solutions of nonlinear neutral dif- ferential equations with variable delays. By changing the differential equation with the related differential inequali- ty, the zero distribution of solutions of the nonlinear neutral differential equation with variable delays was consid- ered, and a lot of known results were generalized and improved.
