Feinstein constructed a compact plane set $X$ such that $R(X)$ has no non-zero, bounded point derivations but is not weakly amenable. In the same paper he gave an example of a separable uniform algebra $A$ such that every point in the character space of $A$ is a peak point but $ A$ is not weakly amenable. We show that it is possible to modify the construction in order to produce examples which are also regular.", "revisions": [ { "version": "v1", "updated": "2004-07-30T14:54:01.000Z" } ], "analyses": { "subjects": [ "46J10", "46H20" ], "keywords": [ "construction", "compact plane set", "bounded point derivations", "produce examples", "separable uniform algebra" ], "note": { "typesetting": "LaTeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2004math......7533H" } } }
