Divergence, thickness and hypergraph index for general Coxeter groups

Pallavi Dani, Yusra Naqvi, Ignat Soroko +1

We study divergence and thickness for general Coxeter groups . We first characterise linear divergence, and show that if has superlinear divergence then its divergence is at…

Conformal dimension bounds, Pontryagin sphere boundaries, and algebraic fibering of right-angled Coxeter groups

Christopher H. Cashen, Pallavi Dani, Kevin Schreve +1

We introduce a graph-theoretic condition, called --branching, that ensures a combinatorial round tree with controlled branching parameters can be quasi-isometrically embedde…

Fractional distortion in hyperbolic groups

Pallavi Dani, Timothy Riley

For all integers and , and all non-elementary torsion-free hyperbolic groups , we construct a hyperbolic group in which is a subgroup, such that the distor…

RAAGedy right-angled Coxeter groups

Christopher H. Cashen, Pallavi Dani, Alexandra Edletzberger +1

We give criteria for deciding whether or not a triangle-free simple graph is the presentation graph of a right-angled Coxeter group that is quasiisometric to some right-angled Arti…
