Abstract

Let A\mathbb{A} be an annulus in the plane R2\mathbb R^2 and g:AAg:\mathbb{A}\rightarrow \mathbb{A} be a boundary components preserving homeomorphism which is distal and has no periodic points. In \cite{SXY}, the authors show that there is a continuous decomposition P\mathcal P of A\mathbb{A} into gg-invariant circles such that all the restrictions of gg on them share a common irrational rotation number (also called the rotation number of gg) and all these circles are linearly ordered by the inclusion relation on the sets of bounded components of their complements in R2\mathbb R^2. In this note, we show that if the decomposition P\mathcal P above has a continuous section, then gg can be linearized, that is it is topologically conjugate to a rigid rotation on A\mathbb{A}. For every irrational number α(0,1)\alpha\in (0, 1), we show the existence of such a distal homeomorphism gg on A\mathbb{A} that it cannot be linearized and its rotation number is α\alpha.
