Abstract

We prove that if GDiff1(R2)G\subset\text{Diff}^{1}(\mathbb{R}^2) is an Abelian subgroup generated by a family of commuting diffeomorphisms of the plane, all of which are C1C^{1}-close to the identity in the strong C1C^{1}-topology, and if there exist a point pR2p\in\mathbb{R}^2 whose orbit is bounded under the action of GG, then the elements of GG have a common fixed point in the convex hull of Op(G)ˉ\bar{\mathcal{O}_{p}(G)}. Here, Op(G)ˉ\bar{\mathcal{O}_{p}(G)} denotes the topological closure of the orbit of pp by GG.
