Stallings showed that a finitely generated group which has more than one end splits as an amalgamated free product or an HNN extension over a finite subgroup. Dunwoody gave a new geometric proof of the theorem for the class of almost finitely presented groups. Here we adapt the method to the class of finitely generated groups using Sageev’s generalisation… (More)
