二阶中立型微分方程解的振动性

Oscillation of Solutions to Second Order Neutral Differential Equations

这篇论文研究形如[x(t)-P(t)x(t-τ)]″=Q(t)x(g(t)),t t0的二阶中立型微分方程的解的振动性。本文归纳和改进了参考文献[2],[3]中关于二阶中立型微分方程解的振动性的理论。

This paper studies the oscillation of solutions to second order neutral differential equations of the form [x(t)-P(t)x(t-τ)]″=Q(t)x(g(t)), tt_0. My conclusion generalizes and improves the theory stated in[2,3].in the reference.
