Abstract

Relative train tracks, introduced by Bestvina-Handel, are convenient representatives of free group outer automorphisms. They serve as analogues of Thurston’s normal form for surface mapping classes. I will describe joint work with Michael Handel using particularly nice relative train tracks called completely split relative train tracks, or CTs for short, to compute some invariants of free group automorphisms.
