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 $I ¨ $ of a g…

Reidemeister numbers for arithmetic Borel subgroups in type A

Paula Macedo Lins de Araujo, Yuri Santos Rego

The Reidemeister number $R (I ¨ )$ of a group automorphism $I ¨ \in Aut (G)$ encodes the number of orbits of the $I ¨ $ -twisted conjugation action of $G$ on itself, and the Reidem…
