Graphical models for topological groups: A case study on countable Stone spaces

Beth Branman, George Domat, Hannah Hoganson +1

By analogy with the Cayley graph of a group with respect to a finite generating set or the Cayley--Abels graph of a totally disconnected, locally compact group, we detail countable…

A hyperbolic free-by-cyclic group determined by its finite quotients

Naomi Andrew, Paige Hillen, Robert Alonzo Lyman +1

We show that the group $⟨ a, b, c, t : a^{t} = b, b^{t} = c, c^{t} = c a^{- 1} ⟩$ is profinitely rigid amongst free-by-cyclic groups, providing the first example of a hyperbolic free-by-c…
