Dimension and
randomness in groups acting on rooted trees
Miklos Abert of University of Chicago
We explore the structure of the p-adic automorphism group of the
infinite rooted regular tree in terms of Hausdorff-dimension. We use
random methods to answer a question of Sidki and solve a problem of
Shalev.
