Hausdorff dimension of some groups of automorphisms of rooted trees (Gustavo Fernandez Alcober, University of Bilbao)

03.05.2022 10:30

Hausdorff dimension is a way of measuring the relative size of a subset in a metric space that has been applied, for example, to measure fractal sets. More recently, it has also been considered in the setting of (countably based) profinite groups. In this talk, we survey results about the Hausdorff dimension of (the topological closure of) some distinguished families of subgroups of the group of automorphisms of a rooted tree.
