AMS, April 2008", "categories": [ "math.OA", "math.FA" ], "abstract": "We report on recent progress in the program to classify separable amenable C*-algebras. Our emphasis is on the newly apparent role of regularity properties such as finite decomposition rank, strict comparison of positive elements, and Z-stability, and on the importance of the Cuntz semigroup. We include a brief history of the program's successes since 1989, a more detailed look at the Villadsen-type algebras which have so dramatically changed the landscape, and a collection of announcements on the structure and properties of the Cuntz semigroup.", "revisions": [ { "version": "v3", "updated": "2007-08-22T20:32:23.000Z" } ], "analyses": { "subjects": [ "46L35", "46L80" ], "keywords": [ "regularity properties", "classification program", "separable amenable", "cuntz semigroup", "finite decomposition rank" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007arXiv0704.1803E" } } }
