Some observations on transitivity of Lipschitz operators

Abstract

The universal property of the Lipschitz-free spaces allows for the linearisation of a base point preserving Lipschitz map $f:M\to M$ to a bounded linear operator $T_f:\mathcal{F}(M)\to \mathcal{F}(M)$. While it is known that the operator $T_f$ is weakly mixing whenever $f$ has this property, it is open whether a similar inheritance result for topological transitivity holds. Motivated by this question we investigate properties of $T_f$ under the assumption that $f$ is topologically transitive. In particular we prove Kitai's theorem for Lipschitz operators, i.e. we show that every connected component of the complex variant of $T_f$ intersects the unit circle if $f$ is topologically transitive.
