摘要
运用Leray -Schauder不动点定理和Liapunov函数方法 ,研究了一类四阶非线性微分方程的概周期解 。
The almost periodic solutions for a class of fourth order nonlinear differential equations are studied by using the Leray-Schauder fixed point theorem and the method of Liapunov functions.We obtain the sufficient conditions which guarantee the existence of the almost periodic solutions of the differential equations.
