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.

关键词: Hamilton系统, 低维不变环面, KAM类型定理

Abstract: The present paper deals with the persistence of lower dimensional tori, the integrable system has a more general form. By intr oducing 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.

Key words: Hamiltonian system, lower dimensional tori, KAM-type theorem
