摘要 研究可积系统的解析摄动 ,即具有更一般形式的 Hamilton系统的低维不变环面保持性问题 .通过一个修改的 KAM迭代格式建立一个 KAM类型的定理 .在前人工作的基础上 ,证明了近可积 Hamilton系统的大部分低维环面没有被摄动破坏掉 ,保持下来的环面可以是双曲的、椭圆的 ,也可以是混合型的 . The present paper deals with the persistence of lower dimensional tori, the integrable system has a more general form. By introducing a KAM iterative scheme, we set up a KAM-type theorem and proved that the majority lower dimensional tori are not destroyed by the perturbation, the survived tori might be elliptic, hyperbolic, or a torus containing elliptic and hyperbobic ones.
