本文证明了在Brjuno-Rüssmann非共振条件下解析可逆映射不变曲线的存在性。证明中利用函数的多项式结构进行截断,引入参数,使KAM迭代的步数在函数的速度上无限小,而不是超指数函数。
In this paper we prove the existence of invariant curves for analytic reversible mappings under Brjuno–Rüssmann’s non-resonant condition. In the proof we use the polynomial structure of function to truncate, introduce a parameterand make the steps of KAM iteration infinitely small in the speed of functionrather than super exponential function.
