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…

Failure of quasi-isometric rigidity for infinite-ended groups
Nir Lazarovich, Emily Stark
We prove that an infinite-ended group whose one-ended factors have finite-index subgroups and are in a family of groups with a nonzero multiplicative invariant is not quasi-isometr…
