Abstract: 

~~
In this talk we will present a model based on random walks for the density of subsets in finitely generated groups.
The main focus will be on the group large sieve method which is a tool for estimating the density by investigating the finite quotients of the group. We will describe applications of this method for linear groups as well as for mapping class groups.
