摘要
主要研究了一类四阶线性具多时滞脉冲微分方程的振动性质,得到了它的所有解和有界解振动的充分条件,其结果推广了文献中Feng Weizhen的结论.
This paper deals with the oscillations of fourth- order linear ordinary differential equations with impulses and multiple lags, sufficient conditions are obtained for all solutions and bounded solutions of the equation to be oscillatory, the results are generalized and the results of Feng Weizhen have been improved.
