Acylindrical group actions on quasi-trees

open access: yes, 2016
A group G is acylindrically hyperbolic if it admits a non-elementary acylindrical action on a hyperbolic space. We prove that every acylindrically hyperbolic group G has a generating set X such that the corresponding Cayley graph is a (non-elementary ...

Coxeter's enumeration of Coxeter groups

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract In a short paper that appeared in the Journal of the London Mathematical Society in 1934, H. S. M. Coxeter completed the classification of finite Coxeter groups. In this survey, we describe what Coxeter did in this paper and examine an assortment of topics that illustrate the broad and enduring influence of Coxeter's paper on developments in ...

Combination theorems for Wise's power alternative

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract We show that Wise's power alternative is stable under certain group constructions, use this to prove the power alternative for new classes of groups and recover known results from a unified perspective. For groups acting on trees, we introduce a dynamical condition that allows us to deduce the power alternative for the group from the power ...

Topological Aspects of Quadratic Graphs and M‐Polynomials Utilizing Classes of Finite Quasigroups

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
Material science, drug design and toxicology studies, which relate a molecule’s structure to its numerous properties and activities, are studied with the use of the topological index. Graphs with finite algebraic structure find extensive applications in fields such as mathematics, elliptic curve cryptography, physics, robotics and information theory ...

Unitary Cayley graphs of Dedekind domain quotients

open access: yesAKCE International Journal of Graphs and Combinatorics, 2016
If X is a commutative ring with unity, then the unitary Cayley graph of X, denoted GX, is defined to be the graph whose vertex set is X and whose edge set is {{a,b}:a−b∈X×}.

(Random) Trees of Intermediate Volume Growth

open access: yesRandom Structures &Algorithms, Volume 67, Issue 4, December 2025.
ABSTRACT For every function g:ℝ≥0→ℝ≥0$$ g:{\mathbb{R}}_{\ge 0}\to {\mathbb{R}}_{\ge 0} $$ that grows at least linearly and at most exponentially, if it is sufficiently well‐behaved, we can construct a tree T$$ T $$ of uniform volume growth g$$ g $$, or more precisely, C1·g(r/4)≤|BG(v,r)|≤C2·g(4r),for allr≥0andv∈V(T),$$ {C}_1\cdotp g\left(r/4\right)\le \

Domination Parameters of the Unitary Cayley Graph of 𝕑/n𝕑

open access: yesDiscussiones Mathematicae Graph Theory, 2023
The unitary Cayley graph of 𝕑/n𝕑, denoted Xn, is the graph with vertex set {0, . . ., n − 1} where vertices a and b are adjacent if and only if gcd(a − b, n) = 1.

A Review on Kinematically Redundant Parallel Mechanisms With Configurable Platforms

open access: yesSmartBot, Volume 1, Issue 4, December 2025.
This review systematically combs the development context and technical system of Parallel Mechanisms with Configurable Platforms (PMCPs). Furthermore, through the progressive logic of classification, analysis and application, the paper reveals how “kinematic redundancy” and “configurable platform” break through the rigid limitations of traditional ...
