微分同胚的不可积性
Nonintegrability for Diffeomorphisms
【摘要】 考虑微分同胚的不可积性.在非共振情形下给出了解析微分同胚存在形式首次积分的必要条件,进而在一般共振情形下给出了解析微分同胚存在形式首次积分的必要条件.
【Abstract】 The aim of this paper is to study the nonintegrability for diffeomorphisms.We first gave a necessary condition for diffeomorphisms to have formal first integrals.Furthermore,we gave a necessary condition for diffeomorphisms to have formal first integrals in the simple resonance cases.
