Non-typical points for $\beta$-shifts

Dynamical Systems 2015-03-17 v2 Number Theory

Abstract

We study sets of nontypical points under the map fββxf_\beta \mapsto \beta x mod 1, for non-integer β\beta and extend our results from [F\"arm, Persson, Schmeling, 2010] in several directions. In particular we prove that sets of points whose forward orbit avoid certain Cantor sets, and set of points for which ergodic averages diverge, have large intersection properties. We observe that the technical condition β>1.541\beta>1.541 found in [F\"arm, Persson, Schmeling, 2010] can be removed.
