Abstract:
In this article, we propose a general normal form to prove the
persistence and the Gevrey-smoothness of lower dimensional elliptic
invariant tori of nearly integrable symplectic mappings under
the Russmann non-degeneracy condition. Our results generalize the
ones presented in the literature.
