Existence of Periodic Solutions with Saddle Point Characteristics for Some Non-Autonomous Second Order Systems

Chen Jin~1,Zhao Fukun~2(1.Department of Mathematics,Zhaotong Teacher's College,Zhaotong 657000,China;2.School of Mathematics,Yunnan Normal University,Kunming 650092,China)  
This paper studies the existence of periodic solutions for some non-autonomous second order systems.The existence theorems of periodic solution with saddle point characteristics are obtained by using saddle point reduction methods.
