Hebrew University Amitsur Algebra Seminar ---------------------------------- Time: Thursday, December 6 , 12:00-13:15 Place: math 209, HUJI Speaker: Alessandro Sisto (Oxford) Title: Statistical properties of groups Abstract: Given a family of objects, it is natural to ask what a typical one looks like. This kind of questions can be usually made precise using randomised models, e.g. random walks. I will give a precise statement along the lines that given a group acting "nicely" on a hyperbolic space, a typical element acts loxodromically. One can deduce that, for example, rank one elements are generic in CAT(0) groups and pseudo-Anosovs are generic in mapping class groups. I will discuss results about typical loops and typical triangles.
