Existence of Invariant Tori in Reversible Mappings.Sheng Qing HU.Abstract In this paper,we study reversible diffeomorphisms with n angular variables and only one action variable.Under some reasonable non-degeneracy conditions,we prove that the reversible diffeomorphisms sufficiently close to the integrable ones preserve a large set of n-dimensional invariant tori.
