title: Unique ergodicity and zero entropy of irregular almost automorphic symbolic extensions of irrational rotations

abstract: A classical result by Markley and Paul states that irregular
almost automorphic systems over irrational rotations are typically not uniquely ergodic and have positive
entropy. By constructing a particular Cantor set, we prove that for each
irrational rotation there still are such almost automorphic extensions which are
mean-equicontinuous (and hence have zero entropy and are uniquely
ergodic). We will shortly review the results by Markley and Paul and then discuss
the construction of the Cantor set.

This is a joint work with Eli Glasner, Tobias Jäger and Christian Oertel.
