Solutions to Bestvina & Feighn's Exercises on Limit Groups
Abstract
This article gives solutions to the exercises in Bestvina and Feighn's paper on Sela's work on limit groups. We prove that all constructible limit groups are limit groups and give an account of the shortening argument of Rips and Sela.
