Borel asymptotic dimension of the boundary action of a hyperbolic group
Abstract:
We give a new short proof of the theorem due to Marquis and Sabok, which states that the orbit equivalence relation induced by the action of a finitely generated hyperbolic group on its Gromov boundary is hyperfinite. Our methods permit moreover to show that every such action has finite Borel asymptotic dimension. This is a joint work with Andrea Vaccaro.
