摘要
在文〔1～5〕的基础上,讨论了一类相当广泛的非线性奇摄动系统,当μ→O^+时,以退化周期解为极限的周期解存在的充分条件,同时讨论了其解的唯一性。
In this paper we study the periodic solutions of singularly perturbed systems in non-isolated case under conditions different from those in [2～5].It should be pointed out that conditions here can include some 'singular' case,and we have not found any papers discussing the 'singular' case before.
