A dendrological proof of the Scott conjecture for automorphisms of free groups
Published online by Cambridge University Press: 20 January 2009
Abstract
Let α be an automorphism of a free group of rank n. The Scott conjecture, proved by Bestvina-Handel, asserts that the fixed subgroup of α has rank at most n. We give a short alternative proof of this result using R-trees.
