Lienard方程零解渐近稳定性的一个弱条件

A weak condition for asymptotic stabilitgy of trivial solution of Lienard equation

研究Lienard方程零解的渐近稳定性.在Liapunov函数V满足dV/dt≤0的情况下,给出了进一步判断其渐近稳定的一个条件.

The asymptotic stability of the trivial solution of the Lienard equation is considered. A condition for the global asymptotic stability is given when the Liapunov function V satisfies dV/dt≤0.
