Generic dense free subgroups of the isometry group of the Urysohn space are NSS
VÃctor Hugo Yañez
The isometry group of the bounded Urysohn space, $G = \mathrm{Iso}(\U{1})$ is a central object in the study of Polish groups and topological dynamics. It is known that generic sequ…

Topologically simple and metrizable free groups with no non-trivial NSS quotients
VÃctor Hugo Yañez
A topological group is said to have no small subgroup (resp. no small normal subgroup) if it admits an open neighbourhood of the identity containing no non-trivial subgroup (re…

Isometry groups and countable groups with the Lévy property
Wei Dai, Su Gao, VÃctor Hugo Yañez
A topological group is said to have the Lévy property if it admits a dense subgroup which is decomposed as the union of an increasing sequence of compact subgroups $\mathcal{G…
