We give a topological framework for the study of Sela's limit groups: limit groups are limits of free groups in a compact space of marked groups. Many results get a natural interpr…

Vincent Guirardel
We give a simple proof of the finite presentation of Sela's limit groups by using free actions on -trees. We first prove that Sela's limit groups do have a free action on a…
