Amenability, exactness and weak containment property for groupoids
Claire Anantharaman-Delaroche
From the mid-1970s, Eberhard Kirchberg undertook a remarkable extensive study of -algebras exactness whose applications spread out to many branches of analysis. In this review…
Amenable actions preserving a locally finite metric
Claire Anantharaman-Delaroche
The class A of countable groups that admit a faithful, transitive, amenable -- in the sense that there is an invariant mean -- action on a set has been widely investigated in the p…
Some remarks about the weak containment property for groupoids and semigroups
Claire Anantharaman-Delaroche
A locally compact groupoid is said to have the weak containment property if its full -algebra coincides with its reduced one. This property is strictly weaker than amenability…
Invariant proper metrics on coset spaces
Claire Anantharaman-Delaroche
It is known that for every second countable locally compact group G, there exists a proper G-invariant metric which induces the topology of the group. This is no longer true for co…
Old and new about treeability and the Haagerup property for measured groupoids
Claire Anantharaman-Delaroche
This is mainly an expository text on the Haagerup property for countable groupoids equipped with a quasi-invariant measure, aiming to complete an article of Jolissaint devoted to t…
Pointwise limits for sequences of orbital integrals
Claire Anantharaman-Delaroche
In 1967, Ross and Strömberg published a theorem about pointwise limits of orbital integrals for the left action of a locally compact group onto , where is the right…
