Finite quotients of spherical Artin groups
Sam Hughes, Thomas Ng, Kaitlin Ragosta +2
We show the smallest non-abelian quotients of spherical and affine Artin groups are isomorphic to the smallest non-abelian quotients of the corresponding Coxeter groups. We deduce…
Relative Cubulation of Small Cancellation Free Products
Eduard Einstein, Thomas Ng
We expand the class of groups with relatively geometric actions on CAT(0) cube complexes by proving that it is closed under --small cancellation free products. We buil…
Separation and Relative Quasi-convexity Criteria for Relatively Geometric Actions
Eduard Einstein, Daniel Groves, Thomas Ng
Bowditch characterized relative hyperbolicity in terms of group actions on fine hyperbolic graphs with finitely many edge orbits and finite edge stabilizers. In this paper, we defi…
Extensions of hyperbolic groups have locally uniform exponential growth
Robert Kropholler, Rylee Alanza Lyman, Thomas Ng
We introduce a quantitative characterization of subgroup alternatives modeled on the Tits alternative in terms of group laws and investigate when this property is preserved under e…
Groups acting on CAT(0) cube complexes with uniform exponential growth
Radhika Gupta, Kasia Jankiewicz, Thomas Ng
We study uniform exponential growth of groups acting on CAT(0) cube complexes. We show that groups acting without global fixed points on CAT(0) square complexes either have uniform…
Hierarchically hyperbolic groups and uniform exponential growth
Carolyn Abbott, Thomas Ng, Davide Spriano +2
We give several sufficient conditions for uniform exponential growth in the setting of virtually torsion-free hierarchically hyperbolic groups. For example, any hierarchically hype…
Conformally Covariant Operators and Conformal Invariants on Weighted Graphs
Dmitry Jakobson, Thomas Ng, Matthew Stevenson +1
Let G be a finite connected simple graph. We define the moduli space of conformal structures on G. We propose a definition of conformally covariant operators on graphs, motivated b…
