Torsion-Free Lattices in Baumslag-Solitar Complexes

M Verma - arXiv preprint arXiv:2406.16196, 2024 - arxiv.org
This paper classifies the pairs of nonzero integers $(m, n) $ for which the locally compact
group of combinatorial automorphisms, Aut $(X_ {m, n}) $, contains incommensurable …

Solvable Baumslag-Solitar Lattices

N Caplinger - arXiv preprint arXiv:2408.13381, 2024 - arxiv.org
The solvable Baumslag Solitar groups $\text {BS}(1, n) $ each admit a canonical model
space, $ X_n $. We give a complete classification of lattices in $ G_n=\text {Isom}^+(X_n) …
