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.
