Abstract

Let h:R2R2h : \mathbb{R}^2 \to \mathbb{R}^2 be an orientation preserving homeomorphism of the plane. For any bounded orbit O(x)={hn(x):nZ}\mathcal{O}(x)=\{h^n(x):n\in\mathbb{Z}\} there exists a fixed point xR2x'\in\mathbb{R}^2 of hh linked to O(x)\mathcal{O}(x) in the sense of Gambaudo: one cannot find a Jordan curve CR2C\subseteq\mathbb{R}^2 around O(x)\mathcal{O}(x), separating it from xx', that is isotopic to h(C)h(C) in R2(O(x){x})\mathbb{R}^2\setminus\left(\mathcal{O}(x)\cup\{x'\}\right).
