Torus actions and automorphism groups of singularities of integrable dynamical systems
Nguyen Tien Zung
We show that in the neighborhood of each ``finite type'' singular orbit of a real analytic integrable dynamical system (hamiltonian or not) there is a real analytic torus action wh…

Nonresonant smooth integrable Hamiltonian systems which don't admit a local smooth Birkhoff normal form
Nguyen Tien Zung
This small note has been withdrawn by the author. The main result of the note, with a corrected proof written in collaboration with a collegue, will be part of a joint work.

Reduction and Integrability
Nguyen Tien Zung
We discuss the relationship between the integrability of a dynamical system invariant under a Lie group action and its reduced integrability, i.e. integrability of the correspondin…
