The Chabauty space of closed subgroups of the three-dimensional Heisenberg group
Martin R. Bridson, Pierre de la Harpe, Victor Kleptsyn
When equipped with the natural topology first defined by Chabauty, the closed subgroups of a locally compact group form a compact space $\Cal C(G)$. We analyse the structure of…
Constructing presentations of subgroups of right-angled Artin groups
Martin R. Bridson, Michael Tweedale
Let be the right-angled Artin group associated to the flag complex and let be its canonical height function. We investigate the presentation theory of the groups…
Subgroup separability in residually free groups
Martin R. Bridson, Henry Wilton
We prove that the finitely presentable subgroups of residually free groups are separable and that the subgroups of type are virtual retracts. We describe a uni…
Subgroups of direct products of limit groups
Martin R Bridson, James Howie, Charles F Miller +1
If are limit groups and is of type $\FP_n(\mathbb Q)$ then contains a subgroup of finite index that is itself a direct product o…
