Minimal subdynamics and minimal flows without characteristic measures
Joshua Frisch, Brandon Seward, Andy Zucker
Given a countable group and a -flow , a measure is called characteristic if it is -invariant. Frisch and Tamuz asked about the existence o…
Characteristic measures of symbolic dynamical systems
Joshua Frisch, Omer Tamuz
A probability measure is a characteristic measure of a topological dynamical system if it is invariant to the automorphism group of the system. We show that zero entropy shifts alw…
Normal amenable subgroups of the automorphism group of the full shift
Joshua Frisch, Tomer Schlank, Omer Tamuz
We show that every normal amenable subgroup of the automorphism group of the full shift is contained in its center. This follows from the analysis of this group's Furstenberg topol…
Symbolic dynamics on amenable groups: the entropy of generic shifts
Joshua Frisch, Omer Tamuz
Let be a finitely generated amenable group. We study the space of shifts on over a given finite alphabet . We show that the zero entropy shifts are generic in this space…
