The Poincare'-Lyapounov-Nekhoroshev theorem for involutory systems of vector fields

arXiv:math-ph/0602052 · doi:10.1016/j.aop.2006.01.002

Abstract

We extend the Poincare'-Lyapounov-Nekhoroshev theorem from torus actions and invariant tori to general (non-abelian) involutory systems of vector fields and general invariant manifolds.
