Peter J. Balint,Ronald E. Stewart,Anand Desai,Lawrence C. Waltersrphism. In the present paper we consider triangle-free simply-laced diagrams. Instead of using Goldschmidt’s lemma, we introduce a new approach by applying Bass and Serre’s theory of graphs of groups, not to the amalgams themselves but to a graph of groups consisting of certain automorphism groups.
