Two remarks on transcendental shift-like maps on ${\mathbb{C}}^N$

Abstract

In \cite{Bedford}, the dynamics of a particular polynomial diffeomorphism of ${\mathbb{C}}^N$, called a polynomial shift-like map of type $\hat{I}½$, has been studied as a higher dimensional analog of Hénon maps. In this note, we prove that the Julia set of their transcendental counterpart is non-empty. In addition, an example of a transcendental shift-like map with an escaping wandering domain has been provided which, in fact, showcases a contrast with the dynamics of a polynomial shift map.
