Hyperfiniteness of boundary actions of cubulated hyperbolic groups
Forte Shinko, Department of Mathematics, Caltech

A classical result of Dougherty, Jackson and Kechris implies that the action of the free group on its Gromov boundary induces a hyperfinite equivalence relation. We will discuss a generalization of this result to a wider class of hyperbolic groups. Joint with Jingyin Huang and Marcin Sabok.
