中文摘要:
      建立一类具比例时滞和正负系数脉冲微分方程解振动的充分条件.所得结果揭示:脉冲微分方程解的振动性可以仅由脉冲条件所引起;在一定脉冲条件下,非脉冲微分方程解的振动性可以被脉冲微分方程所继承.最后举例予以说明.
英文摘要:
      Sufficient conditions for oscillation of solutions to a class of impulsive differential equations with pantograph delays and positive and negative coefficients are obtained.Our results reveal the fact that the oscillatory properties of all solutions of an impulsive differential equation can only be caused by the impulsive perturbations and that the oscillatory behavior of every solution of the differential equation without impulses can be inherited by the impulsive differential equation under certain impulsive perturbations.Some examples are also given to illustrate the usefulness of our main results.
