Isomorphism problem for finitely generated fully residually free groups

Group Theory 2007-05-23 v1

Abstract

We prove that the isomorphism problem for finitely generated fully residually free groups is decidable. We also show that each finitely generated fully residually free group G has a decomposition that is invariant under automorphisms of G, and obtain a structure theorem for the group of outer automorphisms Out(G).
