题目：Existence of invariant tori in reversible mappings
报告人：柳彬教授 (北京大学)
Abstract: 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.
