[Insalate Di Matematica]

Dear all,

For the *next appointment* of the series of seminars "Insalate di
Matematica", *Tommaso Toti* (Università degli Studi di Milano-Bicocca) will
give a talk.
The speaker will deliver the talk *in presence* and the meeting will also
be broadcasted *online* (see below for more information).

Here the details:

*Date and time*: *28th of May 2025, 4:30 pm (CEST)*

*Title*: "Measuring torsion in some pro-p groups"

*Abstract*: Many properties of a group G can be expressed by saying that it
satisfies an equation w(x_1,...,x_k)=1. For example, G is abelian if and
only if it satisfies the commutator equation w(x,y)=1 where
w(x,y)=x^(-1)y^(-1)xy. On the other hand, since we can often turn a group
into a probability space, it is interesting to measure how big/small is the
subset of elements satisfying a given equation. In this talk, we will
discuss this kind of problems for finite and profinite groups and, using
Lie theoretic methods, we will show that the set of torsion elements in
some pro-p groups has Haar measure zero.

*Keywords:* profinite groups, word maps, probabilistic identities

*Information to attend in room 3014*
The seminar will take place in room 3014, at the building U5-Ratio,
Università degli Studi di Milano Bicocca.
