Quantized calculus on Julia sets

Volodymyr Nekrashevych of Texas A&M University

IWe will show how iterated monodromy groups can be used to construct natural Fredholm modules over the algebra of continuous functions on the Julia set of an expanding map. As an application we will generalize a formula by Connes and Sullivan for Hausdorff dimension of a quasicircle to Julia sets of arbitrary sub-hyperbolic rational functions.
