The dynamics of Aut(Fn) actions on group presentations and representations

December 15, 2021
Several different areas of group theory, topology, and geometry have led to the study of the action of Aut(Fn)—the automorphism group of the free group on n generators—on Hom(Fn,G) when G is either finite, compact or a simple Lie group. We will describe some of these. This time mainly the case of G being a finite group.
