Abstract

Let X=(X,B,μ)X=(X,\mathcal{B},\mu) be a σ\sigma-finite measure space and \mbox{f:XXf:X\to X} be a measurable transformation such that the composition operator Tf:φφfT_f:\varphi\mapsto \varphi\circ f is a bounded linear operator acting on Lp(X,B,μ)L^p(X,\mathcal{B},\mu), 1p<1\le p<\infty. We provide a necessary and sufficient condition on ff for TfT_f to be topologically transitive or topologically mixing. We also characterize the topological dynamics of composition operators induced by weighted shifts, non-singular odometers and inner functions. The results provided in this article hold for composition operators acting on more general Banach spaces of functions.
