A groupoid picture of the elek algebras
Publikation: Bidrag til tidsskrift › Tidsskriftartikel › Forskning › fagfællebedømt
We reformulate a construction by Gabor Elek, which associates C*-algebras with uniformly recurrent subgroups, in the language of groupoid C*-algebras. This allows us to simplify several proofs from the original paper and add the converse direction to Elek's characterisation of nuclearity, showing that his sufficient condition is in fact necessary.We furthermore relate our groupoids to the dynamics of the group acting on its uniformly recurrent subgroup.
