We are concerned with the periodic BVP on for the Lienard equation x+f(x)x+g(t, x)=e(t)x(0)=x(T), x(0)=x(T)and Laray-Schauder fixed point theorem is used in the studies of the existence of the periodic solutions.

 
  • 主要利用Leray-Schauder不动点理论研究Lienard方程周期边值问题x?+f(x)x?+g(t;x)=e(t)x(0)=x(T);x?(0)=x?(T)的正解及多个正解的存在性.
