Shift automorphisms of free groups and homeomorphisms of graphs

Coauthors: Venu Addepali Ben Atchison

A SHIFT AUTOMORPHISM of a free group is the analogue of a linear transformation whose RATIONAL CANONICAL FORM has a single block. We address the question of which automorphisms of finite order (or finite outer order) are shift automorphisms. In the process, we develop some useful invariants for HOMEOMORPHISMS OF FINITE GRAPHS.
