讨论一类具高阶Laplace算子的脉冲时滞双曲型方程组的振动性,利用特征函数法和一阶脉冲时滞微分不等式获得了该类方程在2类不同边值条件下所有解振动的若干充分性条件.所得结论充分反映了脉冲和时滞在振动中的影响作用.

The oscillation of the systems of a class of impulsive delay hyperbolic equations with high order Laplace operator is discussed. By using the eigenvalue function method and first order impulsive delay differential inequalities, some sufficient conditions for the oscillation of all solutions of the equations are obtained under two kinds of different boundary value conditions. The results fully reflect the influ...
