Foldings in relatively hyperbolic groups

Richard Weidmann, Thomas Weller

Carrier graphs of groups representing subgroups of a given relatively hyperbolic groups are introduced and a combination theorem for relatively quasi-convex subgroups is proven. Su…

Automorphism groups of combinatorial Hantzsche-Wendt groups

Rafał Lutowski, Andrzej Szczepański, Richard Weidmann

Combinatorial Hantzsche-Wendt groups were introduced by W. Craig and P.A. Linnell. Every such a group , where is a natural number, encodes the holonomy action of any …

Irreducible generating tuples of Fuchsian groups

Ederson Dutra, Richard Weidmann

L. Louder showed that any generating tuple of a surface group is Nielsen equivalent to a stabilized standard generating tuple i.e. where $(a_1,\ldots…

A remark on Whitehead's Lemma

Michael Heusener, Richard Weidmann

We observe that Whitehead's lemma is an immediate consequence of Stallings folds.

Meridional Rank of Knots Whose Exterior is a Graph Manifold

Michel Boileau, Ederson Dutra, Yeonhee Jang +1

We prove for a large class of knots that the meridional rank coincides with the bridge number. This class contains all knots whose exterior is a graph manifold. This gives a partia…

Meridional rank and bridge number for a class of links

Michel Boileau, Yeonhee Jang, Richard Weidmann

We prove that links with meridional rank 3 whose 2-fold branched covers are graph manifolds are 3-bridge links. This gives a partial answer to a question by S. Cappell and J. Shane…
