a-T-menability of groups acting on trees [PDF]
Bulletin of the Australian Mathematical Society, 2004 We present some partial results concerning a-T-menability of groups acting on trees. Various known results are given uniform proofs.

On knot groups acting on trees
Journal of Knot Theory and Its Ramifications, 2020 A finitely generated group [Formula: see text] acting on a tree with infinite cyclic edge and vertex stabilizers is called a generalized Baumslag–Solitar group (GBS group). We prove that a one-knot group [Formula: see text] is a GBS group if and only if [Formula: see text] is a torus knot group, and describe all n-knot GBS groups for [Formula: see ...

Zeta Functions of Discrete Groups Acting on Trees
Journal of Algebra, 2001 This paper generalizes Bass' work on zeta functions for uniform tree lattices. Using the theory of von Neumann algebras, machinery is developed to define the zeta function of a discrete group of automorphisms of a bounded degree tree. The main theorems relate the zeta function to determinants of operators defined on edges or vertices of the tree.

Highly transitive actions of groups acting on trees [PDF]
Proceedings of the American Mathematical Society, 2015 We show that a group acting on a non-trivial tree with finite edge stabilizers and icc vertex stabilizers admits a faithful and highly transitive action on an infinite countable set. This result is actually true for infinite vertex stabilizers and some more general, finite of infinite, edge stabilizers that we call highly core-free. We study the notion

Acylindrical hyperbolicity of groups acting on trees
, 2015 We provide new examples of acylindrically hyperbolic groups arising from actions on simplicial trees. In particular, we consider amalgamated products and HNN-extensions, 1-relator groups, automorphism groups of polynomial algebras, 3-manifold groups and ...

The equation x^py^q=z^r and groups that act freely on \Lambda-trees
, 2009 Let $G$ be a finitely generated group that acts freely on a $\Lambda$-tree, where $\Lambda$ is an ordered abelian group, and let $x, y, z$ be elements in $G$.

On the intersection of tame subgroups in groups acting on trees [PDF]
International Journal of Algebra and Computation, 2018 Let [Formula: see text] be a group acting on a tree [Formula: see text] with finite edge stabilizers of bounded order. We provide, in some very interesting cases, upper bounds for the complexity of the intersection [Formula: see text] of two tame subgroups [Formula: see text] and [Formula: see text] of [Formula: see text] in terms of the complexities ...

Scientia Agricola, 2010 Ecological theories of facilitation and nucleation are proposed as a basis for environmental restoration in tropical ecosystems. The main goal of this paper is to present restoration techniques based on the concept of nucleation, in which small nuclei of
