Dynamical Systems 2024-11-20 v1

Abstract

We will prove a multidimensional conformal version of the scale recurrence lemma of Moreira and Yoccoz \cite{MY} for Cantor sets in the complex plane. We then use this new recurrence lemma, together with the ideas in \cite{M}, to prove that under the right hypothesis for the Cantor sets K1,...,KnK_1,...,K_n and the function h:CnRlh:\mathbb{C}^{n}\to \mathbb{R}^{l}, the following formula holds HD(h(K1×K2×...×Kn))=min{l,HD(K1)+...+HD(Kn)}.HD(h(K_1\times K_2 \times ...\times K_n))=\min \{l,HD(K_1)+...+HD(K_n)\}.
