Abstract

In this paper, we study the so-called Bishop operators TαT _ \alpha on Lp([0,1])L ^ p ([0, 1]), with α(0,1)\alpha \in (0, 1) and 1<p<+1 < p < + \infty, from the point of view of linear dynamics. We show that they are never hypercyclic nor supercyclic, and investigate extensions of these results to the case of weighted translation operators. We then investigate the cyclicity of the Bishop operators TαT _ \alpha. Building on results by Chalendar and Partington in the case where α\alpha is rational, we show that TαT _ \alpha is cyclic for a dense GδG _ \delta-set of irrational α\alpha's, discuss cyclic functions and provide conditions in terms of convergents of αR\Q\alpha \in \mathbf R \backslash \mathbf Q implying that certain functions are cyclic.
