LONG TURNS, INP’S AND INDICES FOR FREE GROUP AUTOMORPHISMS
Résumé
The goal of this paper is to introduce a new tool, called long turns, which is a useful addition to the train track technology for auto-morphisms of free groups, in that it allows one to control periodic INPs in a train track map and hence the index of the induced automorphism.
