Nekhoroshev Estimates for Commuting Nearly Integrable Symplectomorphisms
Jinxin Xue University of Chicago, Chicago, Il, 60637
Abstract:
In this paper, we prove the Nekhoroshev estimates for commuting nearly integrable
symplectomorphisms. We show quantitatively how $\mathbb{Z}^m$ symmetry improves the stability time.
This result can be considered as a counterpart of Moser’s theorem [11] on simultaneous
conjugation of commuting circle maps in the context of Nekhoroshev stability. We also discuss
the possibility of Tits’ alternative for nearly integrable symplectomorphisms.
Keywords:
Nekhoroshev estimates, commuting symplectomorphisms, generating functions, resonances.
