DESCRIPTION:A uniformly recurrent subgroup is a closed minimal invariant s
 ubset in the Chabauty space of a group. After explaining the relationship 
 between uniformly recurrent subgroups and stabilisers of minimal actions o
 n compact spaces\, I will illustrate some examples in which a lack of unif
 ormly recurrent subgroups leads to rigidity phenomena for non-free minimal
  actions.  &nbsp\;  (Joint works with Adrien Le Boudec and Todor Tsankov)
