On Local Tameness of Certain Graphs of Groups

Abstract

Let GG be the fundamental group of a finite graph of groups with Noetherian edges and locally tame vertices. We prove that GG is locally tame. It follows that if a finitely presented group HH has a non-trivial JSJJSJ-decomposition over the class of its VPC(k)VPC(k) subgroups for k=1k=1 or k=2k=2, and all the vertex groups in the decomposition are flexible, then HH is locally tame.
