      Martino, Armando; Ventura Capell, Enric (2004-06)
      Article
      Accés obert
      Let F be a finitely generated free group. By using Bestvina-Handel theory, as well as some further improvements, the eigengroups of a given automorphism of F (and its fixed subgroup among them) are globally analyzed and ...
