      abstract = {This volume presents the lecture notes from the authors  three summer courses offered during the program  Automorphisms of Free Groups: Geometry, Topology, and  Dynamics held at the Centre de Recerca Matemtica (CRM) in  Bellaterra, Spain. The first two chapters present the basic  tools needed, from formal language theory (regular and  context-free languages, automata, rewriting systems,  transducers, etc) and emphasize their connections to group  theory, mostly relating to free and virtually-free groups.  The material covered is sufficient to present full proofs  of many of the existing interesting characterizations of  virtually-free groups. In turn, the last chapter  comprehensively describes Bonahons construction of  Thurstons compactification of Teichmller space in terms of  geodesic currents on surfaces. It also includes several  intriguing extensions of the notion of geodesic current to  various other, more general settings.},
