Properness of nilprogressions and the persistence of polynomial growth of given degree
Romain Tessera, Matthew Tointon
We show that an arbitrary nilprogression can be approximated by a proper coset nilprogression in upper-triangular form. This can be thought of as a nilpotent version of the Freiman…

Horofunctions on graphs of linear growth
Matthew Tointon, Ariel Yadin
We prove that a linear growth graph has finitely many horofunctions. This provides a short and simple proof that any finitely generated infinite group of linear growth is virtually…
