Nielsen coincidence theory for $(n, 1)$ -valued pairs

Karel Dekimpe, Lore De Weerdt

We generalise Nielsen theory to coincidences of pairs $(f, g)$ where $f : X ⊸ Y$ is $n$ -valued multimap and $g : X \to Y$ is a single-valued map, for $X$ and $Y$ closed oriented t…

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…
