Title: Hausdorff dimension and Hausdorff spectra in profinite groups

Abstract: The Hausdorff dimension is a generalisation of the usual concept of dimension

which allows to define the dimension of fractal sets in metric spaces. In the last decades, this notion has led to fruitful applications in the context of countably based profinite groups, as these groups can be naturally seen as a metric spaces with respect to a given filtration.

In this talk we will introduce this concept of the Hausdorff dimension in such groups and we will overview some of its properties. Finally, we will present some results concerning the so-called (normal) Hausdorff spectra of a given profinite group…
