abstract

Given an action of a discrete countable group $G$ on a countable set $\mathfrak{X}$, it is studied the relationship between properties of the associated Calkin representation and the dynamics of the group action on the boundary of the Stone-\v{C}ech compactification of $\mathfrak{X}$. The first section contains results about amenability properties of actions of discrete countable groups on non-separable spaces and is of independent interest. In the second section these results are applied in order to translate regularity properties of the Calkin representation and the topological amenability on the Stone-{\v C}ech boundary within the common framework of measurable dynamics on certain extensions of the Stone-{\v C}ech boundary of $\mathfrak{X}$.

  1. Examples of non-amenable, boundary-amenable dynamical systems

    math.OA 2025-07 conditional novelty 6.0 of 10

    A countable group with the approximation property acting on a countable set with trivial infinite intersections of stabilizers always acts amenably on the Stone-Cech boundary of that set.

  2. On the inclusion $\cO_2 \subset \cQ_2$

    math.OA 2025-05 conditional novelty 6.0 of 10

    The natural inclusion of the Cuntz algebra O2 in the diadic C*-algebra Q2 is C*-irreducible and rigid, so their injective envelopes are *-isomorphic.
