Given a countable group $Γ$ , letting $K_{Γ}$ denote the class of {\pmp} actions of $Γ$ , we study the question of when the model companion of $K_{Γ}$ exists. Berenst…

Borel Combinatorics of Abelian Group Actions

Su Gao, Steve Jackson, Edward Krohne +1

We study the free part of the Bernoulli action of $Z^{n}$ for $n \geq 2$ and the Borel combinatorics of the associated Schreier graphs. We construct orthogonal decompositions…
