Topology Seminar (Introductory Talk): Train tracks for free group automorphisms

Seminar | February 14 | 2-3 p.m. | 740 Evans Hall

 Derrick Wigglesworth, University of Utah

 Department of Mathematics

In this talk, I'll give an introduction to one of the main tools used in the study of Out(Fn): train tracks. These are particularly nice representatives of free group automorphisms that allow one to study their dynamical properties.
