| Oct 28 at 20:30 | comment | added | Diego Martinez | You may find the definition of amenable groupoid (for non Hausdorff étale groupoids as well) in my paper with Buss arxiv.org/pdf/2302.14466 (see definition 4.23). Nevertheless, as Yemon Choi pointed out, non Hausdorffness has nothing to do with separability of the algebra. | |
| Oct 27 at 23:38 | comment | added | PKOA | I took my words back, discard the non-separability, What is the exact definition of non-hausdorff amenble groupoids? | |

| Oct 27 at 17:01 | comment | added | Yemon Choi | I don't follow the reasoning at all. Take any discrete uncountable group, then its reduced Cstar algebra is non-separable. | |
| Oct 27 at 15:32 | comment | added | PKOA | because etale hausdorff groupoids has countable bisections covering any open set | |
