To explain that the condition on the center of the action is not restrictive, we discuss certain abelian groups which in particular, retrieves Theorems of Berend \\cite{Be} and Schmidt \\cite{Sc1} proved in this context.", "revisions": [ { "version": "v1", "updated": "2009-04-06T05:51:45.000Z" } ], "analyses": { "subjects": [ "37A15", "37B05" ], "keywords": [ "compact groups", "contains ergodic automorphisms", "abelian groups", "compact metrizable group", "retrieves theorems" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0904.0848R" } } }
