Subgroups of the automorphism group of a free product
ESB 4133
Wed 7 Oct 2015, 3:15pm-4:15pm


I will discuss classification results for subgroups of Out(Fn) (analogous to Ivanov's classification of subgroups of mapping class groups of surfaces), and more generally of automorphism groups of free products. In particular, I will present a version of the Tits alternative for the automorphism group of a free product. This is partly joint work with Vincent Guirardel.
