摘要
利用Kartastos发展的技巧,研究一类带阻尼项的四阶型脉冲时滞微分方程的解的振动性,给出其振动性的判别准则,并举例说明准则的有效性.
By means of Kartastos technique,this paper deals with the oscillations of fourth order linear impulsive delay differential equations with damping terms.Some criterions for discrimination of the oscillatory property of the solutions to equations are obtained,and one example is given to demonstrate the effectiveness of the criterions.
