Global action-angle coordinates for completely integrable systems with noncompact invariant submanifolds

arXiv:math/0610790 · doi:10.1063/1.2713079

Abstract

The obstruction to the existence of global action-angle coordinates of Abelian and noncommutative (non-Abelian) completely integrable systems with compact invariant submanifolds has been studied. We extend this analysis to the case of noncompact invariant submanifolds.
