本文研究了三阶非线性微分方程+h()+g()+cx=0,h(0)=g(0)=0,c≠0的稳定性问题,用微分矩法构造了Lyapunov函数,并且得出金局渐近稳定性的充分条件。
In this paper, the stability problems of third order nonlinear differential equations + h () + g () + cx = 0, h (0) = g (0) = 0, c ≠ 0 are studied. Lyapunov function is obtained, and the sufficient condition for the asymptotic stability of the golden game is obtained.
