Generalized Baumslag-Solitar Graphs with Soluble Fundamental Groups
摘要
It is shown that the generalized Baumslag-Solitar graphs which have soluble fundamental groups can be constructed from four simple types of graph by a process of decoration. The method of proof is elementary and employs the operations of pinching and contracting edges of graphs.
