The structure and spectrum of Heisenberg odometers
Abstract: Odometers, aka adding machines, are classical and ubiquitous
examples of discrete dynamical systems. In this talk we study odometer
actions of the Heisenberg group. We provide a complete classification of
Heisenberg odometers based on the structure of their defining subgroups. We
also describe how this structure determines the representations of the
Heisenberg group which can arise in the spectrum of an odometer action.
