Given a connected graph, in many cases it is possible to construct a structure tree that provides information about the ends of the graph or its connectivity. For example Stallings' theorem on the structure of groups with more than one end can be pro

Let G and M be groups, and a , b : G → G ∗ M group-theoretic sections of the natural projection G ∗ M → G . We use the Almost Stability Theorem, pro-trees, and new folding sequence techniques to show that if G is finitely generated, then the

We generalize the JSJ-splitting of Rips and Sela to give decompositions of finitely presented groups which capture splittings over certain classes of small subgroups. Such classes include the class of all 2-ended groups and the class of all virtually

A group is accessible if there is a G -tree T such that every edge stabilizer is finite and every vertex stabilizer has at most one end. A group is inaccessible if it is not accessible. In [ 6 ] I began the study of group actions on protrees. These a
