【 摘 要 】
In geometric group theory one uses group actions on spaces to gain informationabout groups. One natural space to use is the Cayley graph of a group. The Cayleygraph arguments that one encounters tend to require local niteness, and hence finitegeneration of the group. In this paper, I take the theory of intersection numbersof splittings of finitely generated groups (as developed by Scott, Scott-Swarup, andNiblo-Sageev-Scott-Swarup), and rework it to remove finite generation assumptions.I show that when working with splittings, instead of using the Cayley graph, one canuse Bass-Serre trees.
