摘要

本文给出了具有若干非单调偏离参数和非负系数的微分方程所有解的振动性的新的充分条件，包括limsup和lim inf。研究了时滞型和先进型的相应微分方程。通过算例说明了该方法的结果及其相对于其他已知振动准则的改进，并在MATLAB中进行了数值求解。

Oscillations caused by several non-monotone deviating arguments

This paper presents new sufficient conditions, involving limsup and lim inf , for the oscillation of all solutions of differential equations with several non-monotone deviating arguments and nonnegative coefficients. Corresponding differential equations of both delay and advanced type are studied. We illustrate the results and the improvement over other known oscillation criteria by examples, numerically solved in MATLAB.
