Sarah Frick, Karl Petersen, Sandi Shields
To study any dynamical system it is useful to find a partition that allows essentially faithful encoding (injective, up to a small exceptional set) into a subshift. Most topologica…

Periodic codings of Bratteli-Vershik systems
Sarah Frick, Karl Petersen, Sandi Shields
We develop conditions for the coding of a Bratteli-Vershik system according to initial path segments to be periodic, equivalently for a constructive symbolic recursive scheme corre…
