Cohomological and quasi-isometric diversity of groups with property $R_{\infty}$

Karel Dekimpe, Paula M. Lins de Araujo, Yuri Santos Rego

How rich is the collection of groups with a given prominent property? In this work we approach this question for property~ $R_{\infty}$ , which says that every automorphism $φ$ of a gi…

Characteristic subgroups and the R $_{\infty}$ -property for virtual braid groups

Karel Dekimpe, Daciberg Lima Gonçalves, Oscar Ocampo

Let $n \geq 2$ . Let $V B_{n}$ (resp. $V P_{n}$ ) denote the virtual braid group (resp. virtual pure braid group), let $W B_{n}$ (resp. $W P_{n}$ ) denote the welded braid group (resp. welded pure…

$R_{\infty}$ -property for finitely generated torsion-free 2-step nilpotent groups of small Hirsch length

Karel Dekimpe, Maarten Lathouwers

In this paper we will show that finitely generated torsion-free 2-step nilpotent groups of Hirsch length at most 6 do not have the $R_{\infty}$ -property, while there are examples o…

The twisted conjugacy growth of virtually abelian groups

Karel Dekimpe, Maarten Lathouwers

In this paper, we study the asymptotics of several growth functions related to twisted conjugacy on virtually abelian groups. First, we study the twisted conjugacy growth function,…
