Dense locally finite subgroups of Automorphism Groups of Ultraextensive Spaces
Mahmood Etedadialiabadi, Su Gao, François Le Maître +1
We verify a conjecture of Vershik by showing that Hall's universal countable locally finite group can be embedded as a dense subgroup in the isometry group of the Urysohn space and…

Homogeneous actions on Urysohn spaces
Pierre Fima, François Le Maître, Julien Melleray +1
We show that many countable groups acting on trees, including free products of infinite countable groups and surface groups, are isomorphic to dense subgroups of isometry groups of…
