Title |
Out(F) and its relatives |
Abstract |
The outer automorphism group Out(F) of a free group of finite rank shares many properties with linear groups and the mapping class group Mod(S) of a surface, although the techniques for studying Out(F) are often quite different from the latter two. Motivated by analogy, I will present some results about Out(F), previously well-known for the mapping class group, and highlight some of the features in the proofs which distinguish it from Mod(S). This is joint work with Matt Clay. |
