Two-generated groups acting on trees

Archiv der Mathematik, 1999
Let \(G\) be a group acting on a simplicial tree \(T\) without inversions, and let the edge stabilizers be non-trivial. If \(g,h\in G\) generate \(G\) (\(\langle g,h\rangle=G\)) or if \(\langle g,h\rangle\) is neither cyclic nor a free product of cyclic groups, then it is proved that the pair \(\{g,h\}\) is Nielsen equivalent to \(\{f,s\}\) and some ...

Pro-p groups that act on profinite trees

Journal of Group Theory, 2008
This paper is concerned with second countable pro-\(p\) groups that act on a profinite tree with trivial edge stabilizers. The motivation for this work lies in the fact that the structure of an abstract group acting on a tree can often be described in terms of the stabilizers and edges of the tree, using the Bass-Serre theory.

Abstract Commensurators of Groups Acting on Rooted Trees

Geometriae Dedicata, 2002
The author has previously constructed a family of finitely-presented, infinite, simple groups, each realized as the commutator subgroup of a group generated by a Higman-Thompson group and a group acting on a locally-finite, spherically-homogeneous tree. The current paper is motivated by the goal of obtaining a more algebraic description of these groups.

Presentation of groups acting on trees with inversions

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1989
SynopsisThe Bass-Serre theory of groups acting on trees without inversions is extended to the case in which the action with inversions is possible.
