We show that the Segal algebra $S(G)$ is left $\\phi$-biflat if and only if $G$ is amenable. Also, we characterize left $\\phi$-biflatness of semigroup algebra $\\ell^{1}(S)$ in the term of biflatness, where $S$ is a Clifford semigroup.", "revisions": [ { "version": "v1", "updated": "2019-05-14T17:51:39.000Z" } ], "analyses": { "subjects": [ "46M10", "43A07", "43A20" ], "keywords": [ "biflat banach algebras", "biflatness", "non-zero multiplicative linear functional", "semigroup algebra", "segal algebra" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
