On the spectrum of $\alpha$-rigid maps

Dynamical Systems 2010-07-08 v4

Abstract

It is shown that there exists an α\alpha-rigid transformation with α\alpha less or equal to 12\frac12 whose spectrum has Lebesgue component. This answers the question raised by Klemes and Reinhold in \cite{Klemes-Reinhold}. We exhibit also a large class of α\alpha-rigid transformations with singular spectrum.
