Equicontinuity, orbit closures and invariant compact open sets for group actions on zero-dimensional spaces
Colin D. Reid
Let be a locally compact zero-dimensional space, let be an equicontinuous set of homeomorphisms such that , and suppose that is compact fo…
Inverse system characterizations of the (hereditarily) just infinite property in profinite groups
Colin D. Reid
We give criteria on an inverse system of finite groups that ensure the limit is just infinite or hereditarily just infinite. More significantly, these criteria are 'universal' in t…
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…
