摘要
本文利用整体反函数理论研究了广义Lienard方程 a(x)x″+f(x,x′)x′+g(t,x)=e(t), x(0)-x(2π)=x′(0)—x′(2π)=0 的边界值问题,得到了周期解的存在唯一性,推广和改进了已有的结果.
By global inverse function theorems, the boundary value problem of a generalized Lienard equation a(x)x″+f(x,x′)x′+g(t,x)=e(t),x(0)-x(2π)=x′(0)-x′(2π)=0 is studied. The existence and uniqueness for periodic solution of a generalized Lienard equation is proved, and the results generalize and improve some known results.
