Generalisable presentations and compactness properties of locally compact right-angled Artin groups
Ilaria Castellano, Bianca Marchionna, Brita Nucinkis +1
We propose the systematic study of presentations that can be generalised over a continuous open group monomorphism. Presentations with this property can turn well-known presentatio…

Double-coset zeta functions for groups acting on trees
Bianca Marchionna
We study the double-coset zeta functions for groups acting on trees, focusing mainly on weakly locally -transitive or (P)-closed actions. After giving a geometric character…

Some invariants of totally disconnected locally compact groups: cohomology and combinatorics
Ilaria Castellano, Bianca Marchionna, Thomas Weigel
The paper investigates two invariants for totally disconnected locally compact groups: the number of ends and the rational discrete cohomological dimension. For such a compactly ge…
