Abstract

Let $g$ be a polynomial automorphism of $\C^2$ . We study the Hausdorff dimension and topological dimension of the Julia set of $g$ . We show that when $g$ is a hyperbolic mapping, then the Hausdorff dimension of the Julia set is strictly greater than its topological dimension. Moreover, the Julia set cannot be locally connected. We also provide estimates for the dimension of the Julia sets in the general (not necessarily hyperbolic) case.
