摘要:

该文考虑了一类高阶线性常系数时滞微分方程y(n)(t) + py′(t) + qy(t-τ)=0的广义振动性和广义非振动性, 给出了一些该类方程广义振动和广义非振动的判定定理. 文中的定理4还给出了一类非振动但广义振动的方程的判别法则.

Abstract:

In this paper, we study the generic oscillation and generic nonoscillation of higher order delay differential equation

y(n)(t) + py′(t) + qy(t-τ)=0.

We provide sufficient conditions for generic oscillation and generic nonoscillation of this kind of equation.

Key words: Generic oscillation, Generic nonoscillation, Leading root.
