Indicability, residual finiteness, and simple subquotients of groups acting on trees
Pierre-Emmanuel Caprace, Phillip Wesolek
We establish three independent results on groups acting on trees. The first implies that a compactly generated locally compact group which acts continuously on a locally finite tre…
Approximating simple locally compact groups by their dense locally compact subgroups
Pierre-Emmanuel Caprace, Colin D. Reid, Phillip Wesolek
The class, denoted by , of totally disconnected locally compact groups which are non-discrete, compactly generated, and topologically simple contains many compelling e…
On the residual and profinite closures of commensurated subgroups
Pierre-Emmanuel Caprace, Peter H. Kropholler, Colin D. Reid +1
The residual closure of a subgroup of a group is the intersection of all virtually normal subgroups of containing . We show that if is generated by finitely many…
