Abstract

Expansion, Random Walks and Sieving in $SL_2 (\mathbb{F}_p[t])$

 

We pose the question of how to characterize "generic" elements of finitely generated groups. We set the scene by discussing recent results for linear groups in characteristic zero. To conclude we describe some new work in positive characteristic.
