Résume | The Nielsen–Thurston theory of surface homeomorphisms can be
thought of as a surface analogue to the Jordan Canonical Form. I will
discuss my progress in developing a similar decomposition for free
group automorphisms. (Un)Fortunately, free group automorphisms can
have arbitrarily complicated behaviour. This forms a significant
barrier to translating specific arguments that worked for surfaces
into the free group setting; nevertheless, the overall
ideas/strategies do translate! |
