| Abstract: |
|---|
| The term "a-T-menable" is a creation of Gromov; it means "more or less amenable, and in any case definitely not property T." The official definition is that a group is a-T-menable if it admits an isometric and metrically proper action on a Hilbert space. I'll explain that in the talk, describe some equivalent definitions, and give examples of a-T-menable groups (among other things, amenable groups are a-T-menable, as one might hope). A notable feature of the class of a-T-menable groups is that the Baum-Connes conjecture is true for all of them . But I won't discuss that (much). |
