摘要
研究了二阶脉冲泛函微分方程解的振动性.通过广义的Riccati变换,利用相关的不等式以及中值定理,得到方程振动的充分条件,并举例说明结论的可应用性.
Some oscillation criteria are established for a forced second functional differential equation with impulses.Using Riccati transform,inequalities and mean value theorem,we obtain the sufficient conditions for the oscillation of the solutions.An example is also given to illustrate the relevance of the results.
