三阶非自治微分方程的不稳定性定理

On the Instability Theorem of a Third Order Nonautonomous Differential Equation

本文运用构造李雅普诺夫函数的方法，给出了一类三阶非自治微分方程零解不稳定的充分条件．

In this paper, we have given sufficient conditions for the instability of a third order nonautonomous differential equation by constrenting Liapunov's function.
