摘要
讨论了一类广义 Lienard型方程 x+f1 (x) x+f2 (x) x2 +f3 (x) x3 +g(x) =0 ,给出了一些充分条件以保证其任何非平凡解为振荡的 。
The generalized Lienard type equation +f 1(x)+f 2(x) 2+f 3(x) 3+g(x) =0 is discussed,and some sufficient conditions to guarantee the oscillating of its any non trivial solution are obtained. Furthermore,the existence of periodic solution is proved.
