We show that when $G$ is compact ZL1(G) is not amenable when G is either nonabelian and connected, or is a product of infinitely many finite nonabelian groups. We also, study, for some non-compact groups G, some conditions which imply amenability and hyper-Tauberian property, for ZL1(G).", "revisions": [ { "version": "v1", "updated": "2008-05-23T18:49:09.000Z" } ], "analyses": { "subjects": [ "43A20", "47B47", "22C05", "22D05", "43A62" ], "keywords": [ "group algebra", "amenability properties", "finite nonabelian groups", "compact zl1", "hyper-tauberian property" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0805.3685A" } } }
